I'm actually having a couple of problems, one of which is that after I wake up, I feel spacey for a few hours. Sometimes when I'm driving I feel "out of it"...this is new. Also, I fill my humidifier every night to the fill line, and it's barely used in the morning, despite having the setting toward the highest. Also, I wake up several times a night either with cold drops of water in the mask, or with a very dry mouth. I've begun taping my mouth, but is it possible I'm still opening it? But what about the moisture in the mask?
