Bitter taste in mouth accompanied by bad breath?

bad breath
Pass_the_peas, please! asked:

I do not know what is causing this gross taste in my mouth. It is bitter, a little tingly, tastes so bad, and makes my breath smell putrid. I am brushing my teeth 3 times or more a day and I gargle with a non-alcoholic mouthwash. Listerine does not work. The taste comes back quickly after brushing and scraping my tongue.

This has been going on for the past two weeks!! I haven’t been eating differently. I have had some constipation and, sorry, diarrhea, but that can’t be it!! i’ve had those before with no stinky breath and bitter mouth problems! What could it be?
