Cooler weather has broght a little bit of comfort while wearing the mask.  I get 2 - 3 hours before I get up to use the toilet.  When I return I don't put it back on and finish the rest of the night without it.  The goal is a full nights sleep using the machine! smiley-cool.gif

Before going to school in the morning I have 15 to 30 minutes of quiet time to my self.  I've been putting on the mask during that time.  It seems to give me better wind when I ride my bicycle to school.  I'm also noticing that my chest is begining to feel fuller on days after I use it and sometimes during the day I wish I had it with me.
