"i been on this adhd medication, but never was on it for more then 3 months. i am always switched due to the weight lose. when i first took it i was about 135lbs, after 2 months i was 98lbs. i lost over 35 pounds. this was in 2010. i stopped taking it because it wasn&#039;t helping me. within those months my doctor kept putting me on different medicines, none worked. i started school with no medicines, i was on the high honor all, my mom wanted me to take it because i couldn&#039;t focus i was so hyper. so my doctor put me on concerta again. i have been on and off, but i have been consistent for 1-2 weeks. i have noticed my face is very itchy and blotchy and i want to hide and cry. well i&#039;m getting good grades but lost 10lbs in a week.
