I never sleep in mine either. That just freaks me out. Even if I had ones that were approved for non-stop use I think it would freak me out. Of course, the thought of jabbing my finger into my eye to put in and remove the contacts freaked me out, too. Now that doesn't bother me at all. So maybe it is something that I could handle.

Ooh I just looked and my lenses are now approved for up to 6 nights wear. Maybe I'll try it.

But I do also wear mine way longer than I am supposed to. I am supposed to change them every 2 weeks but I wear the same pair for months.
