"it&#039;s maybe my 5th week on the drug, noticed an increase in my productivity and feel like i can get a lot done. although i&#039;m suffering from nausea and slight headaches, i&#039;m taking other medications so it&#039;s hard to say. tried ritalin, ritalin xr and dex amphetamine also. this isn&#039;t as aggressive as dex, but dex is my preference in comparison to this. though it&#039;s still early days!"
