My son takes 20 mg of Adderall XR in the morning. Is it true that 6-8 hrs after taking Adderall XR a person can/will experiencing negative side effects, such as withdrawal.
I don't take the XR version, but I have noticed when I do take a big dose in the AM and then miss my 2:00 dose I feel sick to my stomach and very tired.
