I'm currently 18+4 and have a really horrible bitter taste in my mouth that I can't get rid of! I suffer hyperemesis and this taste just makes me feel even more sick! It's not the standard irony taste you hear about, it's a bitter, disgusting taste I can only describe as the taste of morning breath but permanently. I had it with ds but don't remember it being this unbearable 
Has anyone else had this and if so do you have any suggestions? Mints and chewing gum only make it worse! It sounds like a minor problem but it's driving me nuts!
