"i was diagnosed with add about 5 years ago; a year later, i started taking a concerta for 2-3 months; it gave me headaches and didn&#039;t help. hearing good things about adderall i tried it and wow it was like magic. i felt awesome, i could actually think and focus, and everything was great with not-so-terrible side-effects. the thing with adderall for me was that i constantly had to change doses (i tried xr 10, 20, 30 and reg 5,10). i jumped all over the spectrum, because my biggest side effect was it affected my sleep and i was soon diagnosed with moderate obstructive sleep apnea; may not be correlated but it exploited this problem. after roughly 3.5 years the side-effects have increased and it doesn&#039;t help much. looking into desoxyn and dexedrine."
