Mask problem?

[kennyr121]

I could use some advice! Been on treatment for five weeks now. Seems to be working, sleep better, I actually dream now. Problem is for the past two weeks I developed a constant sinus drainage, tickle in my throat, and a cough. Also about two, three times I woke up gasping, not severe, just went back to sleep, this used to happen alot before I started with CPAP. Is there a way to check if my equipment is working right?
