Before I had my back surgery I was on a pretty good dose of fentanyl along with morphine and and one other pain med I forgot plus ambian and a benzo. I wasn’t sleeping all the time. I was quite wide awake and driving. I also was going to swim therapy. I don’t recall the dose but my patch was pretty big compared to the patches others had.

Fortunately surgery took care of the problem and my pain doc was able to wean me off of everything. I still have pain but it’s minor and I take otc stuff now.
