Here's what happened, I was prescribed 10mg of generic Adderall and they were made by Barr and were blue in the shape of an oval. Those worked fine. Although I had taken that amount for a while, I had gotten a little tolerant to them. My doc said he could up the dose to a 15mg tablet. The 15mg tablet is a little round peach/orange colored pill, and I feel like I'm taking a sugar pill. It's not even as strong as the 10mg pill that I was taking. Has anyone else had this experience?
