Hi Momcat,
I believe that Neptazane (Methazolamide) is a good substitute for Diamox if you have a sulpha allergy, but PLEASE check with your doctor and/or pharmacist first, OK? These drugs are just SO similar, I wouldn’t be surprised if a pharmacist knows of some sensitivity for some sulpha sensitive patients… Please let me know!
And it sounds like you all found the ‘secret sauce’ — Zyrtec! I can still have some breakthrough symptoms, but I worship on the Zyrtec altar twice a day…
Big hug,
