I know all drugs affect people differently but most people seem to get broadly similar reactions off E. What i was wondering is why in some people (like me!) a couple of strong pills will cause my jaw to go completely out of control. Some friends are worse than me but some show hardly any gurning effects off several. What mechanism causes the gurning and why do i get it so much worse than so many other people? I never really used to notice it much but i think it's become a lot worse the last few times i've taken it.
