Zyrtec generic reviews and testimonials

In March I avoid going out, it's good that I work from home. Outdoors and when driving a car, I wear a mask. My wife takes a shower and changes her clothes when she comes home. And this system is effective but not 100% working, pollen gets into the house and my lungs. The doctor advised me Zyrtec, I started taking 10 mg every day. Slightly incomprehensible sensations, the drug relieves allergies, but causes strange mood swings. I want to try changing the dosage. Has anyone taken 5 mg twice a day?
