Ah yes, Ultram. I'm on Zytram, which is basically the Canadian version of the same thing. First I was on 150mg slow release, now I'm 300 (working to get back down to 150 now though). Did you originally get relief but your tolerance is up now, or did you never get relief from it?

btw, if it makes you constipated, this can be virtually cured by eating appricots or prunes. Appricots work somewhat better, but they can make you gassy. If you ever need to cure acute constipation, like you have to fix it right now, a sure-fire cure is drinking 1/2 cup olive oil with a 1/2 orange jiuce (the only type of jiuce that covers the awful taste). 1/2 might be a bit intense though, try a 1/4 first.
