I never had allergies till I moved to Virginia when I was in my 40's. Tried everything, nothing worked. My Mom has bad sinus problems, and her Doctor recommended a 'sinus flush' utilizing distilled water and a product called Alkolol. Been around 100+ years, all natural...designed to clean and moisten the nasal canal and sinuses. She swore by it...I started using it, and I have to agree it certainly helps. Takes some time to fully work (weeks), not an overnight remedy, although you'll feel an immediate difference with your first use. I use it seasonally, and then not every day. Some pharmacies carry it, so don't, but will order it for you. You do have to blow/purge the solution up one nostril till it starts flowing out the other side, repeat for the other side. Easy, no as bad as it sounds. You buy a plastic bottle or Neti Pot for this as well (pharmacy), and the kit contains some small powder packets you use as well. Cheap, effective, can't hurt...you don't feel drugged, and certainly helps in my case, especially with headaches.
