"i have add and depression. after several changes in medications the psychiatrist decided to try the methylphenidate and i have not felt this good in years! i am organized, can concentrate and follow through on one thing at a time, have had no problem with my blood pressure at all. it is the same as it was before i started this medication, all mt blood work has been normal every time! i no longer have to take anything to help me sleep!  i no longer have a billion things racing in my head, like you need to do this and that and never following through on anything! i used to do crafts, such as sew, crochet, work in the yard, etc. i can finally do that again! before i was sleeping a lot in the afternoon so then i&#039;d have hard time sleeping at night, but no more!"
