I have been taking Zyrtec for about 2 weeks now to help with an inner ear problem that I just recently realized was due to allergies. I ran out of Zyrtec yesterday and I think I am going to try Claritin for a day or two now. Zyrtec was giving me random shortness of breath spells (only about once a day and my asthma inhaler would usually help the shortness of breath). I also have been having nightmares and my attitude has been very apathetic. I don't feel like my happy self when I'm on Zyrtec. It's better than being dizzy yes, but I am in a relationship and I don't want to feel like I am wasting happy time with my significant other.
