I have been testing out the “Bless You” Allergy Roll On for about a month. I wanted to give it a good amount of time to see how it worked with the increase of Spring blooming (which typically sends me into sneezing fits that don’t seem to stop). I had previously been using Zyrtec 24 hr on a daily basis. I much prefer something natural over all of the chemicals in the OTC medication. So far it has worked like a charm! I started using it only once per day in the morning, but have recently increased it to 2 x daily…and NO SNEEZING! I highly recommend this product, and I am not someone easy to please…lol!
