Girls, hello! I'm feeling a bit sick with phlegm and sore throat. I gargle with Inhaler, but it doesn't last long, then it hurts again. What do you recommend? Also, I can't eat properly. The heartburn is terrible. For two days, I haven't eaten well, and I don't feel like eating anymore. It even feels like it will come out, then it relaxes, and I'm tired already.
