Old posts I know but there is a particular phenomenon I wanted to raise. Recently a day after very moderate MDMA use I had a drink and a smoke before going to bed. When lying in bed trying to sleep I was getting near constant arm twitches which were quite irritating. I therefore concentrated on the spasm in the way I might focus on trying to cure hiccups and low and behold the twitching stopped, however simultaneously (and if felt to me like a consequence of my concentration) I had a fairly strong warm brain zap at the back right hand side of my head. I hate brain zaps, and have rarely had them on MD and therefore felt slightly freaked out. I wondered if anyone had experienced this same phenomenon, and whether it was possible that focusing on stopping the twitches was actually bad in someway for my poor recovering brain!
