I've been dealing with this post nasal drip for the past couple of years and it's really frustrating. There's this thick liquid that's always coming into my throat, and I have to spit it out because swallowing makes me feel like throwing up. I tried taking Lesuride OD75 for a month, like my gastroenterologist suggested, but it didn't really help. On top of that, I have these acidity and vomiting issues. Whenever I get a cold, my nose runs like crazy and the throat thing gets worse. The day after I catch a cold, I end up vomiting all day and struggle to eat anything. The stuff I vomit is so thick, it's hard to get it out. This used to happen just twice a year before, but in the last six months, it's happened four times. I really need some advice on what to do because it's becoming unbearable. What can I do about this?
