The thrust never goes away. I was drinking from the pond. got green message that i am no longer thirsty, less than 5 seconds later it started again "I am thirsty" "I want to drink" "my mouth feels dry" ...etc, i am still in the pond, i drunk out of canteen I had thinking may be the issue is in the pond... but no, I drunk entire canteen and a bottle of water (neither of which were filled from the pond by that point) with no success.
