I would say if you have gone to bed drunk all except 2 or 3 times in the past few months that there is a problem.
No matter how much I tried to rationalize my drinking, looking back, getting DRUNK several times a week is NOT normal...or healthy, and in my opinion shows a dependence on alcohol.
If you don't think you have a problem then go 1 month without drinking and see how it affects you both physically AND mentally. When I stopped drinking (still new to recovery) I did not have ALOT of physical symptoms, however the mental symptoms were out of this world. It was all I thought about. Mental "withdraws" while not as extreme or...painful? perhaps as physical withdraws can still be pretty darn miserable.
