The following may help with the watery eyes.
First take a shower from head to toe and use a mild shampoo. Nothing with to much frangrance or simply just rinse your hair. You have to be free of pollen that may be trapped in your hair.
Change your air filter.
Changer your pillow cases. Especially if you’ve laid in them anytime after coming inside without rinsing your hair.
Put visine allergy drops in your eyes.
Hopefully you also have Witch Hazel. Pour it onto a cotton swatch and squeeze out any excess. You don’t want it dripping. Lay down and close your eyes and place the swatch over your eyes. Oh, I almost forgot, Be sure to clean your face and eyes well before you start. Pay particular attention to your lashes and the corner of your eyes. The witch hazel will help get rid of the swollen lids and cool your eyes.
If you don’t have Witch Hazel, you can try using ice wrapped in a towel. It will do about the same but Witch Hazel will also help get rid of any bacteria hanging around your eyes.
Now for the allergy part you may want to start taking Vitamin C and drink plenty of water. I take 1000 mg when my allergies act up. At the sign of the first tickle in the back of my throat, I take 1 daily till hayfever season is over. I also take Zertec as well but it doesn’t seem to work as well as the vitamin C.
Oh, if you don’t or can’t stay home because of work. Take the pills in the morning and be sure to take some paper towels so you can rinse your face at work when you arrive. Unless your job is outdoors, then you are pretty screwed with the pollen, but hopefully the pill combo will help.
