You haven't offended anyone at all, I just wish I could tell you the magical cure for this. I know for myself all the years I used/drank the anti-depressants would never do much good, and I always had problems with side effects and I hated the "zone feeling" I would get from them. You mentioned he's never taken them longer than a month? It can take 6-8 weeks for the full effect to take over. This is a real difficult situation for you. I can imagine he gets defensive if you mention doctors and medicine, my advice would be to keep working your recovery...he will have to take the steps to get this under control. I really wish I could give more advice, just keep taking good care of yourself. I'll have you in my thoughts and prayers.
Many hugs and hope too,
Tammie
