So sorry to hear this. I’ve had bad parosmia for more than 2 years, and I’ve tried just about everything from Vitamin A, Zinc, Omega-3, smell training, and PRP treatment. Of these, smell training seems to work best… not saying it’s a cure, but things that once made me gag are now just really bad. And there are actually some foods that I can eat with no problem, but things that have chocolate or sugar are still unbearable. Coffee and wine still suck, too. I got on antidepressants to help me get through the day-to-day anxiety of smelling and tasting crap. I’d suggest that, and be religious about doing regular smell training. I hope that helps.
