My son who is 7 was on Adderall XR 20mg. Due to Health Canada prohibiting the sale of this med, my son was put on Dexedrine. I'm not too happy about him taking 2 doese in a day as I think it's way too much. I'm also finding that he has no appetite (he's 54 inches tall and weighs 50lbs). Does anyone know where I can buy the Adderall XR online from a reputable company?
