https://rxchat.com/Discuss/cor-135-20mg-adderall-elimination-time-282376_s2.htm?utm_source=forums_posts&utm_medium=RSS&utm_campaign=RSS Today is Friday. I took 3 cor 135 20 mg adderall. I took 2 at 9:20am and then another one at 2:50 pm. So that's 60 mg in one day obviously. But I'm 156 pounds. Work out regularly and drink lots of water. Can someone tell me how long it would take for this to get out of my system? Thank you - Filed in Adderall en-us Copyright 2026 RxChat.com. All Rights Reserved.

Dividing your original dose by 2s will show 60, 30, 15, 7.5, 3.75, 1.875, 0.9375, 0.46875 .... so let's say about 10 times or more divisions x 11 hours is approx 110 hours or 5 days. I'd say give yourself a week or so. Does anyone else agree or not with my logic? Mon, 2 Mar 2015 04:03:06 GMT
