Red, I am not sure I know why you have these sneeezing episodes. Could it be possible you need a nasal allergy med like nasonex or one of the others? I don't know if you do this but when my asthma became so serious last year I had a special company come in that cleans mattresses and then they treated the mattress with an allergen protective and also cleaned the carpeting and sprayed it with the protectant. I went out and bought all new bedding including the best dust mite covers for my mattress and pillows and all non allergic linens. I know it is expensive but the truth is it is cheaper than all the dr visits I had to make. My pillows have dust mite covers, pillow covers and then a pillow case. I tend to sleep on my side or stomach so my face gets into the bedding. Could this be happening to you? Also, do you have a ceiling fan or any other type of fan in your bedroom? I discovered that the fan I was using had piles of dust between the ridges and my ceiling fan was also very dusty. If you are running fans with dust on them you are breathing that in and that could cause sneezing. I am just taking a guess but maybe this could be a reason. Also, do you change your furnace filters every month? How about the air ducts in your house - do they need to be cleaned? These are all possibilies for what you might be breathing in. I don't know what area of the country you live in but in the Midwest the allergy season has already begun and I am feeling the effects. Mold is the worst for me. You may need to keep windows closed and run your furnace fan or AC. Hope this helps.
