jo123, Hey there! I have a long history of sinus & allergies. Things that work:

1) A cool mist humidifer in the bedroom.
2) Irrigation of the sinus with NeilMed sinus rinse.
3) Elevate your bed with wooden blocks or more pillows.
4) Nasal Ayr Saline spray.
5) Are you on something like Flonase? It helps as well.
6) ENT recommended me to use Afrin 12 hr for 2 days AND COME OFF. You can rebound with this and get worse if you stay on it longer.
7) Polyestyer or any other hypoallergenic pillows. No feather pillows.
8) A pillow case cover for allergies.
9) Wash sheets & pillow cases in hot water weekly....no perfumes. I use All free & clear.
10) Do you have deviated septum on the side of your nose that is blocked? That has to be surgical corrected.
11) The breathe right nasal strips that you put across your nose at night work wonders for some folks that have
trouble breathing. They are on Amazon.

Please ask your doctor before trying any of this. I wish you the best. Blessings & Prayers.....

I question if something in your bedroom is triggering allergies for you.
