Bad sleep cycles will not cause an increase in floaters. See an Eye MD soon (ideally tomorrow) to be sure you do not have retina tear, retinal detachment, inflammation or infection in your eye.

I would advise you to go see an opthalmologist. Since you have been experiencing floaters for awhile now, but have recently been noticing changes go see an eye doctor ASAP just to be on the safe side. Also, it may be helpful to educate yourself about the signs of a retinal detachment.
Your sleep pattern/habits have little to do w/ the floaters.
