I have a seasonal allergy related to pollen. When I was a kid they diagnosed me and the doctor told me to take one pill every day before sleep. I didn't like the side effects of the medication but I just put up with it until I was an adult. One year I started to take one pill every two days during the season and my symptoms were bearable, more bearable than the side effects of the medication. A couple years later I started taking one every three days. Nowadays I take maybe two or three pills a season (4-6 weeks) and only if I feel that an uncontrollable sneeze attack is coming. And yes I tried different brands of this medication.
