Hi, my name is Maureen and I have been using a CPAP machine for three days now. I am wondering if anyone has had this experience and what you have done. I have hearth rhythm issues along with chronic allergies. As such, I can not use any decongestants or antihistamines to clear my sinuses. I have been using saline before going to bed to clear them, but when I wake up, my head is so stuffed up and there is so much pressure in my head. Does anyone else have this issue and what, if any remedies have you used to help? Thanks!
