Starting Vyvanse

So I finally went to a psychiatrist and got a prescription. He gave me adderall, which made my heart race, made me clench my jaw, and had GI issues. I originally wanted Vyvanse because people say it helps. Anyways, did notice some impact of adderall. Didn’t take it for two days because I didn’t like how I felt. Took it in the middle of a binge and was able to think more clearly and stop.

Starting Vyvanse tomorrow. Anyone have experience?
