My doc just prescribed Vyvanse since Concerta seemed to stop working for me. I was taking 54mg of Concerta (couldn't tolerate a higher dose) and have been prescribed 70mg of the Vyvanse to start. Isn't that kind of high? Or do you think I'm starting out on a higher dose because I was on a higher dose of Concerta? This drug has me a little more concerned especially since I'm still weaning off of Lexapro (down to 5mg starting tomorrow). I should be off of it by the end of September. Has any one had experience with Vyvanse at 70mg?
