I noticed if there is no beer in the house, usually I stop drinking.When I stop drinking sleep more and better and feel more creative.
Is just a cycle that needs to be altered.
Edit: And whatever you do talk to your doc.
Tea, milk (which you'll probably want to drink if you're doing any heavy exercising, to gain weight), ice cold water, even wine have been good substitutes for me. I find that I am usually just very thirty, and if I can quench my thirst initially and have something to sip every few minutes, I no longer reach for a beer.
That said, whatever you choose has to be something that you find relaxing. If you find tea or wine to be a hassle and not relaxing, try something else.
