I sure hope this isn't the case. I've been taking the same low dose as you have for about 20 years. Recently I tried the generic with the M on it and after about a week I was in full withdrawal. I have a couple of weeks worth left but the pharmacy told me it is on back order with no date of when it will be manufactured again. Lately I've been in so much pain and the thought of going through weeks of Hell just seems like more than I can handle right now.

If you research the generics, it looks like Teva is a bit better, but I know my pharmacy doesn't carry it.
