IN answer to your question about allergies, i get stuffed up too. I wear a mask when i am cutting grass to help with whatever triggers my allergies to the outdoors problems. One thing that the doctor suggested and also helps tremendously is using a saline nasal spray. I was told to use this 4 times a day especially when i am working outside. We have 21 acres and i cut the pastures several times a year. I have to use the mask when i am doing this to keep from getting a bad sinus headache and of course to keep the stuffiness down to a minimum. Get some of the saline nasal spray and keep it with you and use it. It sure helps me alot. I also take allegra d and it helps as long as i take it on an empty stomach. I take it in the am when i get up and make the hubby's coffee before i eat breakfast and also in the evening when i get home and before supper. It does have a suggestion to take it on an empty stomach. I hope this has been helpful.
