Allergy Changes?

I'm post op day 5 now and I have taken my zyrtec (antihistamine) only once! I forgot one day and then that day I had NO symptoms of environmental allergies. I'm quite allergic to cats, dogs, dust, dust mites etc. I have a little dog. I've only sneezed twice in 5 days (if I didn't take allergy medicine I would sneeze several times an hour and be congested). Has this happened to anyone? I wonder if it would be permanent? 

Glad to hear it.  I don;t recall seeing this in the literature - sleep apnea goes away, but not the same thing.  I'll keep my eye out.  

many things are possible. Being severely overweight causes many health problems besides the obvious ones.
