I have experienced this very thing but with different medications. My pdoc doesn't give me much say in my medications unless I am adamantly of another opinion.

In my case, my pdoc added a stimulant, Vyvnase, to combat the lethargy. To be honest, it hasn't worked wonders. My pdoc has stated he WILL help me overcome this even if he has too additionally add Adderol for a period of time. He says I hyper metabolize medications and that is why it doesn't work as well as it should. I am becoming frustrated with him and his medication choices, however, and am considering changing pdocs. Best of luck to you; I hope you are feeling back to yourself in which ever decision you make.
