Try to wean off your meds, if you can. You'll need ALOT of them to do it. If you have a good rapport with this doc, he can help you wean off. Hopefully, he'll give you a weaning schedule too.
With weaning, you have very little withdrawal symptoms -- believe me, I've done it. It's the best way to do it, with the least amount of discomfort. I'm not saying you won't have ANY symptoms, but they won't be severe like you probably had before!
God bless, my friend, and take care!! keep us posted, will you? I'm with you 100%. Hugs, Lee
