to Rachel: I take 1/2 Tramadol because it is adequate, dulls pain without putting me to sleep. I've never taken a whole one but if 1/2 doesn't work sometime I will try a whole tablet. I take 1/2 of nearly everything (except anti-biotics as they are already weight-calculated) because I am small (115), medicine for an average 250 pound man would be too much for me. I seem to be more sensitive to medicines than other people. Some people in this support group are taking amounts of meds that would kill me but it works for them -- we're all different. Peggy
