Haven't tried it. I am allergic to about 85% of the things for which they test. I grew up sneezing for hours, congested every night. I use to pop about 8 Benedryls a day, just to stay somewhat not bothered by my allergies. When Claritin came out, I jumped on it because it didn't make me goofy-drousy, however, the speed in it would make my mind race at night. I finally ditched the allergy meds and re-evaluated my allergies. I dramatically cut back the foods to which I am allergic. I put dust mite covers on my mattress and pillows. I wash my sheets often. I have no carpet in my house. I have an air filter running in my bedroom 24-7. I try to avoid all cats, as cute and cuddly as they are. My allergies have practically not bothered me at all, unless I break any of these changes. It is amazing, because there have been times in my life when I would have rather died than to suffer any longer from my allergic reaction to things. I now have no very little problem with the windows being open, being outside in nature (except for Pollen Season), and I couldn't be a happier camper, regarding my control over my allergies. I don't miss the things that I have eliminated, because I love the absence of my allergic reactions better than those other things. I think if I had to take a Benedryl today, I might just pass out. I can't believe I used to think that it was my only salvation to free me from my allergy problems.
