My husband hasn't made it to rehab yet -- he still thinks he can quit on his own and, of course, still hasn't. I have learned so far:
1) depression often comes with the first few days/weeks of sobering up.
2) getting sober NEEDS to have a recovery plan along with it in order to succeed.
3) you cannot change his moods or alleviate what he's going through. Put your own physical, mental and spiritual health first.
