At Dr. Dunkelberger’s recommendation for a chronic cough, I’ve been on 10mg Zyrtec (occasionally Claritin) daily for months — since 6 October 2010. I’ve gained 15 pounds. Weird. I just can’t be medicating myself like this. Today I stopped taking Zyrtec.
29 August 2011 update: Instead of daily Zyrtec forever, I started cleaning my sinuses with a NeilMed-brand squeeze bottle. I couldn’t believe what came out of there. Been doing this for most of this year and my chronic cough is completely gone. Only took a few months before it was gone and just a couple weeks before it was markedly better.
