Concerta Poor Kids, Back of My Neck, Muscle Pain, Little Kids, Dry Mouth

trowing up after coming down the medicine .. i dont know if it because i dont get hungry and didn't eat all day while on it , but its not really helping me with my concentration and been active ... i can stay all day in bed not doing anything ..
i have lost 6 pounds in only 2days (which i needed lol cuz i was pregnant) i was 120 now am 114..i dont think its healthy tho, the first day i have a motor tic da it was moving my mouth without even know it and its really hard to stop it cuz u know realize when you doing it, muscle pain in the back of my neck, dry mouth but my lips seem so hydrated and they look really red and soft i have no idea why, its making me memory even worst than when i was w/o the medicine which i need it for school in a week.. if this pill makes me feel so ill i can imgine in a little body like those little kids .. poor kids ... and there i go again repeating myself lol ..
27mg once a day ( in the morning)
