Pregabalin
ibromyalgia
"I've suffered with widespread pain my whole life along with extreme difficulty sleeping. Took Lyrica (300mg/day) for 3 years & it worked initially to calm the aching but became less effective after a few months. It helped me get restful sleep & calmed my anxiety but I couldn't think, had very poor memory & felt very depressed (got worse overtime). When I stopped taking it I had the worst withdrawal symptoms imaginable (way worse than benzos).  I literally felt worse than dying & all I could think of was when the hellish experience would stop . Took about a month to start feeling better & several months to really feel better. Doctors say that Lyrica doesn't have withdrawal (or it should be minor) but that's rubbish. Withdrawal eventually passes"
