Alcoholism and TTC

Once again a negative result but a reason to drink more than I should. Maybe because I'm depressed? Maybe because I'm upset? Maybe I'm losing hope? Or just plain maybe an excuse to get drunk. I am a high functioning alcoholic and have been trying to conceive for 10 months. It's very difficult to talk about it so is there any advice out there or any one like me? Could drinking cause infertility?
