I'm dealing with allergies that hit me whenever there's dust, strong smells, or sudden weather changes. It's been going on for a long time, and I end up sneezing up to 30 times in one go, which is exhausting. I rely on Cetrizine, Fexofenadine, or Bilastine, but every time I take these meds, I get really drowsy and have a dry mouth. Is there anything else you can suggest that doesn't come with these annoying side effects?
