Hey Frick! Welcome back! And congratulations on your continued sobriety. Checking into the rehab. Sounds like it's happening to you pretty much like it happened to me back in 1988. Had a relapse which was so severe that within a week I was close to death with possible irreversible liver damage. Went to a rehab, got started with AA, had aftercare and have been sober now for nearly 28 years. So the stuff that's happened to you sure happened to me.
Believe me, I'm your true friend and have been that all along, with all the other folk on SR. We're all here for you and ready to help in any way we can!
Bill.
