I have recently been diagnosed with mild sleep apnea and the hospital has provided me with a Cpap machine. I have had it for a couple of months but i am still having trouble getting used to it and have never worn it for more than 6 or so hours a night, I will put it on, go to sleep but wake up in the middle of the night and it'll be uncomfortable so i take it off then go back to sleep. Is this normal? Is this enough or should i be wearing ot for the whole night. I currently only have a nose mask and of my mouth opens in the noght it nakrs loud noisecabd wakes my husband. I am thinking of asking to try a full face mask at my appointment on Wednesday. Is there anyone who has tried both? How long did it take you to get used to out and do you wear it for a full nights sleep?
