Dizziness and falling? A couple of years ago my doc put me on tramadol for my back pain. Within days I couldn't close my eyes in the shower for fear of falling over, I almost fell downstairs three times in a week as my legs suddenly gave way under me and I suddenly felt extremely unsafe behind the wheel. If I missed a dose I got severe withdrawal symptoms within a couple of hours, like a cross between flu and near-death. That was all in a period of two weeks. After I'd put two and two together and tried to stop, I spent three demented, totally sleepless nights thrashing about on the sofa. I wasn't back to normal for weeks. I could tell you much more by way of, er, stuff I don't discuss online. Sod tramadol. Evil stuff.
