Just wanted to say Hi since I'm new to the forum. I've been using CPAP for 7 years ( I think it was called Respironics Sleep Easy). Recently I started having a lot of sleepiness and tiredness during the day and overall very groggy in the morning. I went back to my sleep Dr and he suggested having another sleep study done since this guy decided to put on an additional 25 lbs!
Long story short I ended up with a new machine, Resmed 10 CPAP and my setting went from 8 cm to 10 cm. He mentioned that 7 years ago my Apnea was considered moderate and that now is severe. I just got it a little over a week ago and the jury still out on it.
