Party in my GI tract!

Ya know... I'm fully aware of the fact that I shouldn't be drinking out of this water bottle. It's funny smelling and it has water that has been sitting in it for the past couple days (in the hot car). I tried to dilute the water with fresh water to hide the smell but it didn't work. I was so thirsty that I just didn't care. I figured that not breathing out of my nose would do the trick. I wonder how bad my GI will pay for this. This is bad. Really bad.
