I have tried the nasal strips with little success. The congestion is further up the nose. I am usually open all day. Around 8pm or so, I notice some stuffiness and I am not in the bedroom. I had a blood work allergy test that showed nothing. I do keep my cpap accessories clean. You tell me how a doctor can analyze his patient in 5 to 10 minutes. I know he was not listening to half of what I said. He heard Neosynephrine and jumped right on that. I told him I had taken the generic Flonase since 2012 and noticed no benefits and yet he perscribed Xhance, which is the same stuff in a high tech applicator at $600. I did not accept that Rx. I guess I look for #6 ENT doc.
