Allegra and antihistimines

I have been using Allegra for over 2 years. It worked for my allergy symptoms. There are side effects I experienced but didn't really make the connection until I started reading everybody else's experiences. I had headaches, ear aches and ear infections that wouldn't go away, leg cramps at night a foot cramps while driving. I was on several antibiotics for the ear infections. Severe headaches/brain fog at doses of 180. I tried an experiment by stopping the Allegra. Sure enough my ears have cleared up and no more leg & foot cramps. The down side is that my allergies are worse and I have been taking the old antihistamines Chlor-Trimeton & Benadryl.
