this is a topic that I can relate to very well unfortunately. I come from a long line of alcoholics and I grew up watching the effects on my family. I had my times in my youth where I would drink socially, which grew into me trying to drink as much as I could and usually not handling it too well. I don't know how to explain it but at some point I just looked at myself and told myself that I can't do this anymore. I did not want to have the same life as the others in my family had, and I was not going to put my family through this. For whatever reason it worked for me this way, maybe it was all of the al-anon meetings and other meetings that my mom made me sit through. My dad ended up quitting drinking for 15 years before he passed away and he actually helped alot of others find sobriety as well. It is a tough thing to battle against especially with it being so socially accepted.Think of it this way, if you have the willpower to DIET and workout so hard to get yourself in shape and stay in shape then you should be mentally strong enough to keep that in control as well.
