Well, it was pretty good for about a day and a half. I can't stand the stuff. There is no way I could drive if I continued use. Sleep is disrupted, and after a dose of the stuff, I am overwhelmed a need to sleep. Already the dosage must be increased in order to be effective. The stuff is terrible. Long term use is out of the question. Addiction is too easy, although I don't see how anyone could stand the stuff. It really makes my head feel strange, but my thinking remained clear. I want to keep it that way, so either it goes on the shelf for drastic emergency use, or I flush it and the sewer rats from here to the treatment plants will be euphoric for a while! So I guess I will just continue to work through the pain when I can. No way will I try a narcotic pain reliever again. I don't think I used it long enough to suffer withdrawal, but I will soon find out!
