I have allergies and sinus issues and goshdamn I hate winter with the gas pack heat.
I even use biotene for dry mouth and wake up like concrete.
I've been using a nasal rinze for the past year or so, and it's helped my nasal issues big time. I got the idea from gotgame.
I re-use a 3oz nasal rinse/squeeze bottle that had a saline solution in it, I think from walmart or rite-aid...just generic brand. This one right here:
Mine is 3oz (88ml), so slightly bigger than the one in the link.
I emptied out the contents. I add warm water to it + 1 heaping teaspoon of table salt + 3 small squirts of J&J baby shampoo. Stir it up, tilt my head back, and gently squeeze the solution into one nasal passage at a time. Blow it out, then do the other side. I do that 1-2x each, every morning. I have not been sick hardly at all, and my nasal issues are pretty much gone. It feels good afterward too. I usually don't have to refill until after 3-4 days of use. The solution that is in there, I put the bottle into slightly boiled water to heat up every morning. OH.....and I had to widen the air opening a little using the tip of a fork.
I think gotgame uses a cup and sucks his up with a 20cc syringe. I think he does it morning and night.
I thought it was looney when I first read it, but i had nasal issues ever since I took the covid shots in 2021. Within a few days, I could tell a HUGE difference. It's a complete must for me now.
