Hi, I'm 43 & in hospice bcuz of CHF. Lately, I haven't been able to hold anything down. I'm not dehydrated (IV in the arm) but I'm extremely thirsty, and it seems nothing quenches my thirst after I take a drink I actually feel more thirsty. And when my mouth gets so dry like extremely dry, I get nausea, dry heave, then up comes bile ( the same thing is happening out the other end & same color/no smell I am told) I'm guessing that's bile too.
