"i just started taking it for two day and i hate it the first day i started twitching and shaking and my stomach felt so uncomfortable.the second day it felt worse i had a dry throat, uncomfortable stomach, less twitching , i felt so useless.  the worst thing about it was a post to make me focus and it does not even help. i just hate how i have to lie about how i feel - i say i&#039;m ok but i&#039;m so for from being ok."
