This is a wonder pill, as far as I am concerned. After suffering through several sinus infections earlier this year, my doctor suggested that I take an over-the-counter daily allergy medicine. I won't mentioned which I take, but some days, that alone is not enough. Although the sinus infections ceased, I would still have the occasional runny nose and the awful headaches. On those days, I take Advil Congestion Relief. It's not an every day thing, but at least once a week, when the pollen count is high outside, this is my miracle pill. I have offered it to friends and family who also suffer with allergy issues, and they love it as well. A co-worker just tried it this week (yes - I carry them in my purse) and he was amazed at how his sinus congestion magically disappeared. Needless to say, I HIGHLY recommend this product. If there were ten stars available - I would rate it ten out of ten!
