Does anyone else get this?

I have noticed over the last week or so that no matter what I have to drink, I find I have a strange taste in the back of my throat, and on occasions a weird sensation?

When i get up in the morning  I have a glass of water, and after it has gone down it feels like I have had something almost chalky, and it leaves a funny taste in my mouth.  It's only water so I can't understand it, but sometimes if i have had a glass of fizzy orange or lemonade it does the same.

I have it right now although I haven't had a drink for a while.  I also get a feeling as though I have very weak heartburn.  I was just wondering if anyone else gets feelings like this?  I dont get it after I eat, it's only when i drink, and it can sometimes be quite painful.

I have heard that a proliferation of bad bacteria in the intestines can cause a bad taste in your mouth--especially in the mornings after it's set all night.  When I was having my daily diarrhea problem, I had this weird taste in my mouth that toothpaste just wouldn't touch.  In fact, I woke up with an even worse taste in my mouth if I brushed my teeth at night; I think maybe making my mouth clean just made the taste all the more noticeable the next morning.

I don't know if I had bad bacteria or not, but I no longer have the D problem daily and my mouth no longer has a weird taste.
