Hi everyone! Okay so I am prescribed to 20mg XR adderall and have been since September. The first couple months I would take 40mg a day for a week then stop until my next script came in. Starting last month I would take 40mg around 9 then another 20mg at 11. Today I decided to take 40mg at 745, another 20mg at 845, then 20 more at 1045. How long will it last me and what should I expect from it in my later hours around 5 or 6? How will the comedown be and what should I do to make sure I stay safe with it? I am 6'1 190 pounds and can usually handle my adderall really well. I have a class from 1-2 but after that I will be in my dorm for the remainder of the day. Thank you!
