P.S. Heather - I also use lomotil as many times as I need during the day: If I'm going out, I take two (And deal with dry mouth! Sometimes it's hard to talk without sounding like you're drunk! But, it helps) and I take one lomotil before bed. That slows things down.
Because I also suffer from some osteoarthritic pain and neurologic leg pain, I will use tramadol at times . (I don't want to get addicted to it so I don't use it very often) Because it's an opiate, it does constipate and it really helps!
I know some people use tincture of opiate. You need to ask your doctor about that. I bought some, but I really haven't used it much.
