Hi! Everyone,
Being thirsty is often a side effect of meds, and Lord knows we all take enough of them. Drinking alot is ok, but fluid intake and urine output need to be balanced/equal, for optimum wellness. You can sometimes tell that your fluid intake is a problem if your legs and feet swell. And we lose fluid from our intestines, too. If your mouth and lips feel dry, then some moisturing lip gloss might help, too. I have taken care of alot of patients who were NPO, which means we couldn't let them eat or drink. I have found that holding sips of water in your mouth, or ice chips, as long as you can, so the water drizzles down your throat, rather than a swallow or guzzle, might help you feel less thirsty. And it wouldn't hurt to be sure you mention this to your primary care doctor. 
Sometimes we inadvertently create a habit for ourselves, and there are alot of calories that hide in pops and tea drinks. The antioxidants in teas are very healthy. I like to steep green tea and then add fresh sprigs of mint, and then use less sugar. Be sure to crush or twist the mint to release the mint oil. I was given 1 small pot of mint, was cautioned it tends to overtake everything in it's reach, planted it along the semisunny side of my house, and have a patch of mint that now supplies 3 neighbors! Lemon or lime in the water might help soothe your thirsties, too. Polydipsia, too much thirst, is one of the 3 major signs of diabetes, so your doc will check that often. Hope you have a long stretch of feeling better, soon
