I two 20 mg XR per day for over a year (one before breakfast, one in afternoon)--worked fine. Currently I'm taking one XR in a.m. and one IR in p.m. which is a little more versatile. I prefer the real Adderall to the generic (IR), so I may ask to be switched back to taking two XR's per day.
HAVE YOU THOUGHT ABOUT VYVANSE? A LONGER IMO BETTER FORM OF ADDERALL. WE HAVE BEEN ON IT FOR 4 WEEKS AND IT HAS HELPED SOO MUCH W/O ANY REBOUND OR SIDE EFFECTS AFTER THE 1ST 2 WEEKS. I WOULD HIGHLY RECCOMEND IT TO ANYONE TAKING ADDERALL XR MORE THAT 1X A DAY.
