alcohol withdrawal
"I have been drinking alcohol seriously for 40 years.  I have stopped drinking before but always had cravings and eventually went back to drinking.  This time I have not had cravings and don't even think about alcohol the majority of evenings.  This has only been going a month now so take that into consideration.  I read something about baclofen and alcohol withdrawal 2 days ago and recalled that my back doctor had given me a prescription for it and I have only taken it 2 or 3 times this month.  I have been curious as to why I have not had any cravings.  Perhaps it was the few Baclofen I have taken."
