My mental productivity and agility is vastly improved of late, as I have begun to take amphetamines as needed. As little as 10mg of extended-release mixed amphetamine and dextroamphetamine salts keep me alert through the day, while allowing at least 6 hours of restful sleep each night. The difference this has made in my prospects, the acheivability of my goals, has been tremendous. I can actually process information, overpowering the miasmic shackles of mental depression by sheer power of vital and dynamic will. This is a Good Thing.
