Side effects - Facial Tics!!!

[Dreamland]

Everytime SWIM takes adderall (in doses 30mg and higher), SWIM gets constant eye blinking, and jaw jacking.. Sometimes it bothers SWIM when out partying.. other times SWIM doesn't even know it's happening until SWIM's friend brings it to his attention and says "SWIY look like a F*ckin tweakers, stop that shit!".. SWIM tries, but goes back to it....when it comes to adderall, SWIM nevers really knows if too much has been taken unlike with downers(SWIM breathing will get slow)...

SWIM is curious, why amphetamines do this? Does SWIY ever have this happen to you? SWIM's assuming there's not way to get rid of it except look "normal" in public.

SWIM drives safe, so no worries about getting pulled over by the cops.. but then again, SWICops will just think SWIM has tics or tourettes...
