Is it safe to take two zyrtec (cetirizine) a day, one in the morning and one at night?

In brief: Sedation

That dose of zyrtec is going to be very sedating.
This defeats the purpose of taking zyrtec instead of benadryl (diphenhydramine). That level of sedation will make you a drowsy --> dangerous driver. Have you tried Loratadine or allegra? Do you use Flonase or something like it? Do you regularly flush your nose with a saline/ baking soda solution?
