Nikon is my suggestion. I shoot an XTI currently. the problem with canon is that the lenses are super expensive. With a nikon you could get the camera and a multiple lenses where as with the canon one lens would cost you a limb.
ive got apo zopiclone pills. they work okay but the next day i feel really drowsy. the most important thing ive ever done to help my sleep cycle is to stay away from the computer for at least an hour before going to bed. but that didnt last long...
