Dextroamphetamine

"I'm a rare case; I currently am prescribed 180mg of Adderall (90mg IR & 90mg XR). When this was raised to 240mg, I asked to try Dexedrine thinking that after a decade on Adderall, I had simply become tolerant to it. My doc put me on 120mg of Dexedrine. There was a noticeable decline in my focus, and my energy levels (not that's why you should take stimulants) fell off the map. It was smooth. But for me, it was way too smooth. I remember taking 60mg one morning and then going for a hike. I couldn't concentrate on a damn thing, and I was nodding off as I was walking. I guess I should have expected this going from such a high amount of Adderall to a lower dose of Dexedrine (which is absent of levoamphetamine). I would try it again though."
