I am also wearing new gas permeables (because of my astigmatism).  My 
optometrist's advice was to wear my lenses for as long as they are comfortable.
This is usually 13 - 16 hours or so for me.  There has been a few occasions 
when I fell asleep whilst having the lens on, and when I woke up boy 
do I feel the lenses like rocks under my eyes!
