Great Product
I love this product. Hay Fever, Allergy and Sinus (H.A.S.) is very effective for seasonal allergies. I take just one a day in the morning. I don't suggest that you take any after 4PM. While I have never felt it to be a stimulant, but have found that taking it at night gave me a restless sleep (this is my observation only...). Love love love the product. I discovered it when I lived in Texas with all the dust and use it now in the Seattle area with all the rain and mold.
