Works The Next Day
I've been taking Zyrtec 4EVER!!! My new allergy doctor put me on Xyzal. It does work and I do sleep better at night without all the congestion in my nose.  I do suffer with allergies and this over-the-counter allergy medicine is one to try out.  I think you will be surprised when you wake up with clear head.  Just remember to take it at bedtime.
