Quick, cheap, decent diaper? I'll be ordering down the line, but...

I'm sick (up all night congested) and every time I "doze off" and wake back up, I have to pee. (we're talking about every 1/2 hour to 45 minutes)

My options are Safeway, Wallgreens, and MAYBE rite-aid
(I will probably order from Northshore later on, but for the time being)
