Kim has been on Provigil for years, it's a real HUGE help for her.
She started out on 100 and was moved up to 200 a few months later, this was maybe about 9 years ago. She takes it in the morning and it gives her more "day". There are no down sides to this, unless you accidentally take one before bed
This also makes me think of something we recently learned about caffine. It turns out that cryptic CPn is a possible explanation of caffine crash or induced "MS" symptoms. I'm a caffine user, I need caffine. Some MS'ers have a unique caffine profile wherein you get a temporary burst, but then crash hard. (not the caffine addict profile) Kim was like that and it turned out to be CPn related. Just sharing.
