ADHD
"I&#039;m a rare case; I currently am prescribed 180mg of Adderall (90mg IR &amp; 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&#039;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&#039;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."
