Maybe you're not taking the right theraputic dosage. I've been on and off of Adderall a few times. Mainly because I build up a tolerance for the drug, and then bam! I'm taking 90 mg a day.......-_-

I'm taking Dexedrine SP currently, but I've tried all the other drugs out there, and I can honestly say stimulants help better than non-stimulants. Mostly because it negates the sleepiness I encounter from all of my other meds.
