Meperidine / promethazine
pain
"I have Ehlers-Danlos syndrome and I am in at least 6 or 7 level pain most of the time without meds. A lot of pain meds make me nauseated or leave me woozy.  For some reason Meprozine doesn't make me feel light headed at all and the phenergan in it keeps me from being nauseated.  I was able to go to college and graduate with honors because I actually felt like doing something!"
