I came on here a couple of months ago asking for the opinion of the forum on much the same thing, not about drinking on my own but regarding a habitual drink or two most evenings.
I was told that I was 10 years from death and that I had a very serious problem. To be honest I kind of regretted asking, lots of effort went into in fighting and petty squabbling and you have to remember this is a forum full of healthy types and puritanical arses.
If you suspect that you are getting into trouble, you quite possibly are but it also displays a degree of self awareness that may serve to act as a regulator. As AA say, the hardest bit is admitting you have a problem, if you are not averse to admitting that you might have a problem I would suggest you are in a strong position to act in a way that improves your life and your helps you do the things you want to do, not just the things that habits draws you towards.
FWIW, I have stopped drinking altogether on school nights, it has been relatively easy and I have lost some weight and saved some money but only a modest amount of each. I do look forward to letting my hair down on the weekends which I am sure some people will interpret as me having a serious drinking problem but I stay sobre more often so I am in good shape to ride my bike, apparently I have a serious biking problem too!
Good luck in whatever you do, if it gets too bad I can put you in touch with some very good people who can help depending on where you live. Email is in the profile.
