Thanks for the info - seeing an ENT is also on my todo list. I never realized this was an issue until recently, but looking back I've always been a mouth breather. One night a few weeks ago I tried the method of taping my mouth shut before going to sleep. I woke up the next day feeling super sick and lightheaded, presumably due to lack of oxygen. There definitely seems to be an issue with my nose breathing.
