So I stop drinking and instantly have a lame health problem. Ok, so I'm sure the 2 things are unrelated, but still...what the F?

I came home from work early and had to take some sleeping pills to knock me out, so glad it worked. Now I'm up and feeling a bit better. I'm really hungry, but don't know if I am up for going to the store or not. I should just take some more pills and wait until tomorrow morning. I have a doctors appointment and I realized I have no insurance card, I wonder what is going to happen?
