adhd
"I'm a 24 year old male. I was on Adderall XR 30mg (daily) for around 3-4 years before my Doctor suggested we try Vyvanse. I have always been pleased with Adderall XR and have no complaints about side effects. Vvyanse (60mg daily) worked as advertised for a about 3-4 days. It was like an upgraded Adderall XR (provided a longer half life that is much needed for my schedule of college and work). Unfortunately, the drug drastically lost its effectiveness. The dry mouth was extreme as well. After just 10 days taking 2 at a time had no effect. Went back to adderall xr and I'm still impressed."
