Restoring sense of smell after losing it from too much magnesium is easy, but it burns a bit. Lots of cold cures include magnesium. I've lost my sense of smell twice using magnesium in nasal gels and cold lozenges. Just go to any drug store and get one of the capsaicin nose sprays, like Sinus Buster, at Walgreens or Walmart or CVS or wherever. They are used for sinus issues and migraines and cluster headache attacks. Just use as directed. Smell came back pretty quickly; I think it was the same day I started the capsaicin spray. The ones I still have in the fridge are Allergy Buster, Sinus Buster, and Headache Buster. I use them for cluster headache attacks. But I no longer use magnesium for colds, as it aggravates my cluster headache attacks.
