I’d need to be pretty danged banged up to let the doctor prescribe that stuff to me again. I was using it after a surgery last year, when I had 7 weeks in a wheel chair. The high is fine, and combined with Ibuprofen it will kill a significant amount of pain, but the constipation can literally kill you after a few days on it. And there’s definitely a strong “down” when you stop taking it. A bad combo, which explains the addictiveness.
I know a couple people who work at our local pharmacy. They tell me that is how they know who the heavy users are because they are always buying heavy duty Exlax.
Heck, more than two Advil in 24 hours will do that to me - I don't know how people deal with the heavier pain dugs.
