pain
"For migraine pain = BEST = obliterates an attack.
Side effects = Severe = dizzy and sedated, tolerance develops rapidly with any repetitious use. I take Stadol to abort only the most severe migraine attacks, about 10 doses per year. 

I can take it, but only if I have absolutely NO responsibilities for the 4 following hours.  Stadol has helped me avoid a trip to the ER numerous times. It's one of those "break glass in case of emergency" type medicines, for me.  It works EXTREMELY fast, starting in less than 2 minutes."
