Tramadol
"I feel a need to give a personal warning against Tramadol. They are not kidding when they say it’s a STRONG drug. 



I had, to some degree still have, problems with bad general anxiety, and accompanying bad pains which were oddly un-located, sort of All Around. (I’ve only recently learned that this is not unusual and doctors can’t help apparently.) So I tried all kinds of different drugs from the Net. One which I felt made a difference was Tramadol. So I used it for several years, getting up to insane doses like six hundred mg daily, partly because it didn’t *really* help overall but only suppressed the pain for some hours and then it came back worse."
