First off, I would like to give my condolences to those who came into this thread hoping to flame some sorry soul looking to get high off o promethazine.

Well, basically I have a filled script of promethazine from who knows when that, in a recent bout of extreme restlessness, has been recycled into a sleep aid. However taking even 50mg, if I recall correctly as I really don't care to go through it again, gave me terrible twitchiness that kept me up and agitated to extremely uncomfortable degrees. Would mixing this with like 1 Benadryl, which I know to also cause said twitchiness have some type of additive effect and twitch me out as though I had taken too much of either?
