Realized gum is helping with nausea!

So I don't know about you but I always have this weird sour taste in the back of my tounge that just makes me sick!!!! I've struggled with the nausea some days worse than others but no crazy vomiting or anything. I'm 10 weeks 3 days and nausea has gotten worse!!! I gag all the time it is so annoying But noticed that chewing on gum eases that weird taste in my mouth and helps with nausea!!! And cold water with ice!! So weird what I have discovered lol
