Hi telesius,
As others have said, it is only u who can really decide- and that is not aways easy when everything hasn't been lost etc. I know im an alcoholic, but cos im 20, never really drank in the morn (apart frm a few times) and didnt drink all day everyday i can get doubts. I also find it hard to accept - but many do. What it comes down to is the control. In the Big Book of A.A. it says something along the lines of, if when you start drinking you have little or no control you are probably alcoholic. Also if you find, when you want to stop, you cannot fully - you are probably alcoholic.
If i ever have doubts now and feel confused - i just remeber those very lines. It not about how much u drink- or when in the day u drink, how often u drink- NONE of that - it's what happens when u drink. Its feelings of guilyt, shame, remorse the next day after another binge. It's the hopelesness. I hope this helps u decide. I wish u well.
