I haven’t been diagnosed with sleep apnea and I’m not even sure I have it, but I’ve been having an ongoing issue for three years now where whenever I fall asleep, my mouth gets ridiculously dry. I can feel it getting dry as I’m drifting into my sleep even though my mouth is closed. I have confirmed that mouth breathing isn’t the cause as I’ve tried mouth tape and it still happens. I’ve also tried using a humidifier, sinus rinse, biotene mouth wash and toothpaste, drinking lots of water (especially before bed), eating healthy and low salt, but nothing seems to work.
I’ve seen an ENT doctor for it, and all he’s suggested is doing surgery on my nasal passages since they are narrow. Not sure how much that’ll help though if mouth breathing isn’t the cause.
I have been driving myself crazy trying to figure out what the cause/cure is, and I was wondering if anyone else has experienced the same thing as me, and what they have done to fix it.
Side note: I was on Wellbutrin (an SSRI antidepressant) 3 years ago, around the time this issue started. I went off after 6 months though, and haven’t been on any SSRIs since. Dry mouth is a common side effect of Wellbutrin, but I’ve been off it for well over 2 years and it’s still lingering, but only when I fall asleep.
Any help or personal anecdotes are greatly appreciated.
