I was diagnosed as adhd 2 years ago at the age of 38. I started at 20 mg 2xdaily immediate release. I worked my way up to 30 mg 3xdaily. Just today my Doctor took me off the 30 mg pills and put me on the 20mg pills. Does anyone know if there will be any kind of side effects from the dosage getting changed. I am just worried that's all.
