I know that this is a sceptics forum but is two months without alcohol an extended period?
At this time the one friend i am think of has not had a large amount of alcohol since December. And he does not have any of the functioning problems associated with alchol. When he is drinking it is normaly a drink or two a couple times a week. But when he is socializing with people who drink heavily then he drinks very heavily. The incident i mentioned was an example that happened about six yeras ago when he had neighbor friends who were periodic heavy drinkers as well. His current heavy use is about eight drinks.
And you just have to take my word, there is no impairment in his daily functioning.
Believe me, I know what that is about, the individual I am thinking of is very functional, the periods of heavy drinking come mainly from the social area he is in.
I am not sure which three you are referencing, I personaly use behavioral criteria for addiction (although i have not done assesment since changing jobs seven months ago.)
We could go round all day on this. You now added that one of these bingers drinks a couple times a week whereas earlier, it was "they go for extended periods without any use or overuse of alcohol". Even that statement, use or overuse is a contradiction.
People who drink a lot consistently underestimate how much they drink. People who drink a lot and recognize it to some degree, commonly hide some of their drinking. People who drink a lot or who are friends/family of alcoholics underestimate how much the drinker consumes.
I cannot say what is the situation with the people you are describing. So let's discuss the indicators of disease, patterns of use and the issue of denial and underestimating consumption both by the drinker and by those around them.
Diagnosis:
Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV)
DSM-IV: Substance Abuse criteria
A pattern of substance use leading to significant impairment in functioning. One of the following must be present within a 12 month period: (1) recurrent use resulting in a failure to fulfill major obligations at work, school, or home; (2) recurrent use in situations which are physically hazardous (e.g., driving while intoxicated); (3) legal problems resulting from recurrent use; or (4) continued use despite significant social or interpersonal problems caused by the substance use. The symptoms do not meet the criteria for substance dependence as abuse is a part of this disorder.
DSM-IV: Substance Dependence criteria
Substance use history which includes the following: (1) substance abuse (see above); (2) continuation of use despite related problems; (3) increase in tolerance (more of the drug is needed to achieve the same effect); and (4) withdrawal symptoms.
Alcohol Use Disorders Identification Test (AUDIT)
Drug Abuse Screening Test (DAST)
Prevalence of abuse and dependence including a bar graph showing 1 or more DUIs does indeed predict abuse and dependence. See figure 7 (since I brought that issue up earlier.)
The U.S. national average for alcohol dependence is 4.4% with males at 6.3% and females at 2.6% (NIAAA, 1994) [9]. This increases to 9.7% for “current drinkers” [10] (Males = 11.3%, Females = 7.6%). Overall, the national average for females is about half that of males. However, females (11.1%) had about the same rate of dependence as males (12.3%)
So my 10% figure was about right if you exclude non-drinkers.
You can have abuse without dependence and rarely, dependence without abuse. See figure 8
Denial and under-reporting of amount of alcohol intake:
The Denial and Awareness Scale (DAS)
"Furthermore, one of the key facets of addictive behavior is denial, not only by the addict, but by the family as well....The denial process starts gradually and occurs as the family begins to compensate for the substance abuser."
The under-reporting of alcohol use: the role of organic mental syndromes.
"Denial of alcoholism is a serious obstacle to the successful treatment of an alcoholic. If clinicians can conceptualize and focus on this denial, they may be able to make more effective interventions with alcoholics. Denial in alcoholism, as in other illnesses such as cancer and heart disease, may encompass denial of the entire illness or only denial of some aspect, such as the loss of control over alcohol consumption."
Patterns of drinking and clinical course of alcoholism:
"Periods of abstinence following the onset of alcohol dependence in 1,853 men and women...Data from both laboratory experiments and retrospective histories of alcoholics indicate that alternations between periods of abstinence and heavy drinking are common in the course of alcoholism. This article examines the prevalence, chronological characteristics and clinical features associated with periods of abstinence in a large sample of alcohol dependent men and women."

WHO/ISBRA Study on State and Trait Markers of Alcohol Use and Dependence:
analysis of demographic, behavioral, physiologic, and drinking variables that contribute to dependence and seeking treatment. International Society on Biomedical Research on Alcoholism....alcohol-dependent subjects consumed more alcohol than nondependent subjects, alcohol consumption increased with age...the category designated as heavy drinkers (>210 g alcohol/week)...although men drank more than women on a g/day basis, the differences were less pronounced on g/kg/day basis, and alcohol-dependent women drank equal amounts of alcohol as alcohol-dependent men on a g/kg/day basis. Antisocial personality characteristics or reports of trouble sleeping when an individual stops drinking were associated with higher alcohol intake. The most important of the tested factors that contributed to a DSM-IV diagnosis of dependence, however, was the report of anxiety if an individual stopped drinking. In terms of the various criteria within the DSM-IV criteria for alcohol dependence, no one criterion seemed to be prominent for individuals who sought alcohol dependence treatment, but the higher the number of criteria met by the individual, the higher was the probability that he or she would be in treatment.
The 5-year clinical course of high-functioning men with DSM-IV alcohol abuse or dependence
....This study evaluated the ability of the DSM-IV categories of alcohol abuse and alcohol dependence to predict the onset and cessation of the 11 DSM-IV abuse/dependence criterion items. METHOD: The DSM-IV categorical approach was used to determine alcohol diagnoses for 435 highly educated young adult men, who constituted 97.3% of the 447 men appropriate for this study. Structured face-to-face follow-up interviews were administered 5 years later. RESULTS: At the beginning of the study, 14.5% (N=63) of the subjects were alcohol dependent, 18.2% (N=79) reported alcohol abuse, and 67.4% (N=293) carried no alcohol diagnosis. Across these three diagnostic groups, 68.3%, 46.8%, and 15.4%, respectively, experienced at least one of the 11 DSM-IV abuse/dependence criterion items over the next 5 years. Only 11.4% of those who reported alcohol abuse went on to develop alcohol dependence. In addition to their diagnosis, characteristics that predicted subsequent problems with alcohol included a family history of alcoholism, higher levels of alcohol intake and a greater number of alcohol problems in the 10 years preceding the diagnosis, and a history of drug use. CONCLUSIONS: Even in this highly educated and high-functioning group of men, alcohol abuse and dependence predicted the onset and cessation of alcohol-related problems.
Patterns of DSM-IV Alcohol Abuse and Dependence Criteria Among Adolescents and Adults: Results From the 2001 National Household Survey on Drug Abuse
...Overall, the most prevalent criteria of DSM-IV alcohol dependence were "tolerance" and "time spent obtaining alcohol, drinking, or getting over its effects." The most prevalent criterion of DSM-IV alcohol abuse was "hazardous use." The prevalence of alcohol abuse only and of dependence with and without abuse was highest among respondents aged 18-23 years, followed by respondents aged 12-17 years, and lowest among respondents aged 50 years and older....Conclusions:
The higher prevalence for some dependence criteria among adolescents and young adults as measured in the present study may blur the distinction between symptom reports associated with the normative development of drinking patterns and clinically relevant aspects of DSM-IV alcohol dependence.
So, the patterns of drinking you describe can occur in younger men but if they continue for the decades as you describe, it is extremely unlikely to be in the absence of dependence or abuse or both. It's much more likely you are underestimating how much these guys are drinking in between heavy drinking. And with the amount you are describing in the heavy drinking, tolerance is clearly involved.
Take a look at
figure 10 in this citation I noted earlier. The higher you get your blood alcohol in a drinking binge, the more likely you are to be dependent.
