I 've been tormented by ragweed allergies since I was a child. I hated taking chemical antihistamines but I felt helpless. I feel like there is light at the end of the tunnel since beginning immunotherapy with Pollenguard. The treatment is a commitment but I made the drops part of my daily routine and have not had to use antihistamines and decongestants. This is my second hayfever season and progress has been steady, my symptoms lessen each month and every season. My allergist says next season I may not need any drops or allergies at all.
