I have had severe allergies all year long for many years. The congestion and sneezing would never stop. I tried about everythng and it only would mask or help me for a very short time and still be miserable and couldn't sleep at night feeling so congested. Every little smell of anything was triggering my allergies and sneezing to the point I didn't want to do much at all. When Nasacort came on the market I figured I might as well try it too, after all what could it hurt at this point. I am sure glad that I did. I have been so thrilled that I do not suffer from the symptoms that I had before. I can breath and do my normal things without always having to stop and blow my nose. After doing the initial 2 sprays in each nostrol for a week and then went to one spray, I now only use one spray about twice a week and still have felt great. I would recommend trying this product if you suffer from a lot of congestion and sneezing from allergies. And no side affects at all!
