... schedule changed we decided to add some XR's to the mix. I suggested 15 XR's and 15 IR's. When I picked up my prescription it was 15mgs for both XR and IR, I guess my doc got confused. I called him and he said he's not allowed to prescribe me anymore until my next appointment, one month. I know these 15 mg pills aren't going to do anything for me, is there anyway I could make the effects of Adderall stronger until I get my prescription figured out?
