I hope you're drinking a lot of water because even if you don't experience hang overs, your body will still be dehydrated from that. You may have an addictive personality, which means you might have to replace the alcohol with something else, like you did with the cigarettes, but you need to get to the bottom of why you have an addictive personality - what do you want in your life that you aren't getting so you're reaching outside of yourself for comfort or for instant gratification? What feeling do you keep assuming coffee, beer or cigarettes will give you that you feel you cannot generate yourself naturally on your own (because you can, by the way)? Make sure the next addiction is a healthy one. You can switch your addiction to music playing, a health food lifestyle, vegan hot tonics, hookah (which I hear is better for you than smoking cigs), going to the gym, creating art, juicing, find something you actually like and replace the beer with that, but then also work on why you keep chasing after that feeling that you desperately feel you can't generate without "something". Its not easy, because we all do it one way or another. You just need to be conscious about it. And do this with your gf, tell her you want to really cut down on your beer drinking.
