The only reason I'm not an alcoholic is because I don't want to be overweight.
Why is weight gain the only thing stopping you from becoming an alcoholic?
Starving myself would be a better option than eating too much then I can drink what I like.
It's great that you're able to resist temptations, but if potential weight gain is the only thing keeping you from alcoholism then you may have some issues that need to be addressed. When we find ourselves drawn to substance-abuse, it's usually a sign that we need help. Consider seeking out therapy or support group.
I don't want therapy. I'm fine and just want to drink to my heart's content.
It sounds like you are drinking in place of eating instead. You shouldn't become an alcoholic and if you are you should get some help. You don't want alcohol to take over your life.
