My Dr switched me today from 40mg of ir Ritalin to 30mg ir adderall. Its not BC of anything bad just doesn't feel its strong enough and wasn't comfortable upping dose again. Now I should also note that I suffer from low energy vs high which is another reason for change. She gave me the freedom to play with way I take it as long as I didn't go over the prescribed dose per day. So instead of 20mg 2x a day I was more comfortable and had less drop offs taking 10mg 4x a day. Can I do that with adderall as well? These are 15mg pills. I guess I'm worried about the drop off like I had with Ritalin. Any advise suggestions or input would be greatly appreciated.
