Yes I had trouble again with the LSAT.

I was unable to sleep the night before the test and I barely slept the previous night. I also developed chest pain in the morning and was unable to drink any coffee, so suffice to say I was not in much of a state to take a 4 hour test where speed is a necessity. So yeah another score canceled.
So I have one last chance for late admissions and I know there is no chance in hell I'll sleep the night before the next test. I thought the only sensible thing to do was to order some Modafinil. This drug is intended to treat narcolepsy, but it has been used for other purposes. Some people use this stuff as a nootropic. The French, American and British militaries use it to keep their people awake. In one study helicopter pilots were kept awake for 88 hours on this stuff. Sleep deprived F-117 pilots performed near baseline levels while taking modafinil.
Anyway does anyone have any experiences with this drug?
