I take adderall (dextroamphetamine and racemic amphetamine) 25mg xr an it seems like after 6 hours i eat an hour later i feel bad sick been on it for 6 months but skip days?

Common side effect: Nausea, loss of appetite and stomach pain are common side effects of adderal xr, and because of that you are skipping the dose for days. I will recommend you discuss it with your healthcare provider who prescribed the adderal and he/she may consider switching to a different medication.

Alternatives: If Adderall hellps you focus, consider an alternative like methulphenidate (ritalin, concerta). Other alternatives include provigil, nuvigil, wellbutrin, (bupropion) imipramine, strattera. These may allow for better tolerance.
