Like the author said, I've never noticed any physical withdrawal, but I have a strong urge to have a drink every night (sometimes even in the middle of the day). This is one of the most stressful times of my life and it's so hard not to just say "fuck it" and give up. And even when I don't really have that strong of an urge, I'm haunted by rationalizations and second guessing: "just have one," "moderate drinking isn't bad for you," etc. I'm trying to do more self tracking to prove to myself that the last one is BS.
What really sucks is I've noticed that a few beers will cause me problems with dehydration, weight gain, horrible sleep (I'm told I always freak out in the middle of the night after drinking) and yet I've developed such a tolerance that I don't even get buzzed unless I'm on an empty stomach.
