I am a 20 year old college student and I have had ADD for the past six years and have been changed medications about four times since. I started with 20mg of Concerta, then switched to 50mg of Vyvanse, then 60mg of Vyvanse, then I started to feel depressed and I wasn t having the same focused effect as when I first started with Concerta 20mg. So, now I m taking 52mg of Concerta and it kind of works but not as effective as 20mg of Concerta when I was first put on medication six years ago. Also, today I have a lot of work to do, and I took one pill of 52mg of Concerta at 9am, and took another at 1pm because I thought it would give me an extra focus boost, and all it has been doing is make me feel like I have a pain in my heart because it feels like its moving really fast. What do you recommend I should do?
