Welcome!
If you haven't already, now would be a great time to get checked out by a doctor. I know you feel that the withdrawal symptoms you're going through aren't as bad as you've read, but pain near the liver (the liver has no pain receptors, the pain you feel is from the swelling and/or fluid being excreted by it) is very very serious and should be checked out. Maybe get some blood taken to make sure you're not dealing with anything that should be treated.
It gets better.
