I would still repeat, that if anyone is genuinely alcohol dependent, there is a risk of fitting if you simply stop consuming alcohol. Of course, the majority of people who simply drink too much are not at risk if they abstain from alcohol. If however, an individual has been drinking large amounts for a sustained period and - as mswp rightly points out - there are symptoms of dependence such as craving for alcohol on awakening, then it is never advised to simply stop drinking. A thorough assessment by a health professional would be required to ascertain the level of the problem. If the tremors subside after further alcohol is consumed, this is possibly an indicator of alcohol dependence but, without having any depth of detail, very difficult to say. Also, you can't generalise on amounts of alcohol consumed: "only if you are drinking a quart or more a day" as sex, body weight, metabolism, liver function etc., will all have a bearing on what determines a safe amount of booze. I'm from the UK and worked in the health profession. In my experience, detoxing was only an intervention from necessity and not simply for somebody who drank a bit too much. In this context, it is not simply stopping drinking but having measures in place to alleviate unpleasant - and potentially dangerous - withdrawal symptoms.
