When I said fairly, that meant every night, but I'm a stripper and would take the crazy thing off and throw it on the floor.  I used to do the same thing with carpal tunnel gloves.  I wake up and don't remember taking anything off. 

That said, as far as the provigil is concerned, my husband has a script for it and it doesn't really help him at all.  I'll stick to my stacker 3 and 5 hour energy drink if I have to drive more than 15 minutes. 

BTW, my husband is currently in the hospital; it's going to be a while before I get back here again.
