Hi Greg,
Your question is such an important one. So much so that I have just written to Dr Sinclair (with a copy to Dr Eskapa) drawing their attention to your thread. As soon as I have a reply, I'll let everyone know.
Best wishes.

Hi Greg,
OK, I now have a reply from Dr Sinclair. Firstly, the questions I put to him:[1] Why weren't the clinical trial participants drinking at a level that is more representative of that which would be expected of someone suffering from alcoholism?
[2] Is it reasonable to assume that someone with a long history of drinking at high levels would take longer to be "cured" by TSM than someone with a short history of drinking at low to moderate levels? Is there any data available in support of this?
[3] Repeating the original question - does TSM work for heavy drinkers? Once again, is there any evidence in support of this?
One final point. Your reply will obviously be of considerable interest to forum members. Do I have permission to copy your reply to the forum?
This is the reply that I received, which Dr Sinclair gave me permission to reproduce in its entirety:Pharmacological extinction works for anyone who wants to have greater control of their drinking, providing only that it was the opioidergic system that is primarily concerned with providing their reinforcement from alcohol.
Indeed, we have suggested that the method might be promoted as a means of prevention rather than reversal of excessive drinking. If a person (or one of our rats) were to take naltrexone before drinking, they would never develop alcoholism in the first place.
One of the problems in treating alcoholism is the stigma society (incorrect) associates with it. Many people refuse to enter treatment, even though they could benefit, because they do not want to wear that scarlet letter A for alcoholism on their foreheads. They might, however, find it easier to enter treatment that will prevent them from developing alcoholism.
As you know, naltrexone does not help all people. Apparently there is some other system that provides the reinforcement for alcohol drinking for some people. The data show that there are about 10-12% of the people who take naltrexone appropriately but do not, even after several months, obtain a reduction in craving and drinking. I suspect that a similar proportion of heavy drinkers would not benefit from naltrexone. The vast majority of heavy drinkers, however, will have a major reduction in their craving and drinking. Naturally, it will not be as large as the reduction produced in severe alcoholics simply because there is not nearly so far to go. But they will benefit.

So, there you have it.
