Hi @kwal. Know you've read a lot so hopeful this new to you 🤞. First simple try of vitamin c gummies, only couple a day low sugar…, can cut into small pieces to suck on throughout day. Other that helped me tremendously was food/drink anything consumed diary with any change in cough mucous or any other reaction🙃. Histamine was my new item to avoid and then a trained nutritionist for accurate/tailored consumption help for you🤞. Quickest recovery wishes🌈
