I have been on Dexedrine for almost 20 yearss. I am 70 years old and was diagnosed at 50. Sometimes I don’t take it for a couple of days and the first 2-4 are rough in that I am tired and hungry. All that rebound stuff. +When I had hip surgery I had to be off for a couple of weeks and as the days passed, it got easier to cope with. But it isn’t easy – but do it slowly – less medication each subsequent day – don’t do cold turkey – good luck.
