"march 2010-2014 poor concentration &amp; spelling, can&#039;t do math in head. tingling feet, twitches in fingers and lips. in a daze like ozzy osborne. but avg weight loss 2-3 lbs/week no lifestyle changes. dr gave adderall for concentration helped but needed ambien to sleep. was thinner than in highschool, got annoyed with relying on pills gained my 38lbs back &amp; 25 more. i do recommend the medicine, make sure it doesn&#039;t effect your work life, and use vitamin b12 to get rid of the tingling  i&#039;m starting the meds again, the side effects are worth it to me! ;)"
