Zyrtec and ear infection

This is my first time taking Zyrtec D. It was recommended by my local pharmacist. I have had a terrible sinus infection which has lead to a massive ear infection. The ear infection is getting worse . every time I blew my nose, I felt like my ears were going to pop right off my head. Anyhow, the only thing that has made me feel better is Zyrtec D however the side effects I am experiencing from this are far more worse and are not worth it. I am very anxious to the point where my muscles ache. I also have excessive crying spells and I also have been super angry all day. I have taken 2 pills in the past 24 hours. My ears are still clogged but my nose is clear. I am also experiencing shortness of breath and increased heart rate. I also can not sleep and I keep waking up with horrible dreams. I have been searching the internet now to figure out how to get this drug out of my system. Although I can now breath, the side effects are not worth it. I would rather have a stuffed nose then ever take this again.
