Alcoholism is a disease. I don't know that an alcoholic can really ever drink again without slowly letting the demon take over again. I suppose one could if they say, 'I will only drink a maximum of 3 drinks in one sitting every 6 months' and then they stick to that. The problem is, is that those 3 drinks turn into, 'ahh, just one more won't be a big deal', and then it becomes, 'oh, I did fine last week, I if just have one drink this week it won't be a big deal', and so it keep going on and on, until you find yourself back again where you left off when you last quit. Some can do it ... probably most can't. It takes a lot of will power. If you failed at quitting smoking, then you will probably also fail at quitting drinking, or doing drugs -- if you start again. Besides, that shit makes you look old.
