"worked okay but caused fainting spells. coming off of it (tapering, per doctor&#039;said orders) was terrible. i&#039;ve been told more than once that the way i felt sounded like a heroin addict coming off heroin. i was sick to my stomach,  my entire body was in constant pain, every joint and muscle, headaches, i felt cold one minute and burning up the next, exhausted but couldn&#039;t sleep, nightmares when i could catch a few minutes  and periods of wishing someone would just put me out of my misery. this drug  is dangerous! imagine if someone ran out and couldn&#039;t taper off.
