i can't fall asleep when i need to.. help

my eeg was hopeless. i couldn't fall asleep, even though i got up this morning at 2 am. i didn't even nod off at my computer while i was sitting at it at 2 am. i couldn't even fall asleep at my eeg appointment, the computer monitor thing that was hooked up to my head didn't show anything because i wasn't sleeping (a lady put some patches on my head to see if my brain was producing any cells or rehabilitating itself- i don't know how to describe it). i tried everything to fall asleep, counting in my head, deep breathing, trying not to think- everything. the eeg went on from 8 am to 11 am, all that time of me trying to fall asleep. after that, i had an mri, i don't know if the results to that will be clear either. i kept having spasms in my left hand and i don't think that you're supposed to move when you're having mri's. i really wanted some results from my eeg to show whether my brain is rehabilitating. there has to be another way of how to tell whether you have any brain movement or whether or not it's rehabilitating. my axis case manager will probably have a shit fit when she sees that i didn't fall asleep at my eeg AGAIN. i've had 2 eeg's and i couldn't even fall asleep in either of them. you'd think that i would fall asleep or at least nod off since the eeg today was sleep deprived. there has to be another way of telling if my brain is rehabilitating itself.. i just need to find it out.
