At 43, I now have to work harder to concentrate. 11 steps to a better brain sounds good to me.

Modafinil can keep a person awake and alert for 90 hours straight, with none of the jitteriness and bad concentration that amphetamines or even coffee seem to produce.

90 hours?!? Longest I went without sleep was three days and, at the end of it, I threw up before plunging into ZZ land. Not sure if I actally fell asleep or simply fainted my way into it. I am happy to say I can't duplicate that feat now but wouldn't mind giving Modafinil a try. Mixing Modafinil with Levitra would be interesting too. LOL.
