"My son is 13 years old and has have been on Adderall for about 6 years now and was recently switched from Adderall XR 15 mg to Adderall XR 20 mg. Today is his first on the 20 mg. So far he noticed a large difference in the effects. He said when he was on 15 mg XR for 2 years and he didn't even notice his attention span had dropped and his grades had also been, He said felt no effect whatsoever from 15 mg. The 20 mg has a noticably large increase in effectiveness . For the first time in months he feel back to normal and refreshed. He said never knew my body could grow a tolerance to a medication so quickly. I am curious if every dosage will get weak like the 15 mg. I don't want to keep elevating the strength for him as I'm worried it is bad for his health."
