I was thinking it was more the taste of salt in your mouth that triggered thirst rather than the ingestion of it. If it is, and pills were effective at bypassing that it could be a big help to me because I have trouble controlling my thirst.
On the other hand, I have managed to overdo it on the salt once or twice and it’s not too pleasant. Not the worst thing in the world, but I did feel sick. If you’re just eating it you sort of work your way up to that point. I am kind of concerned about taking it in a pill and having it hit you all at once.
I thought about getting some blank gel capsules and making my own salt pills but it turns out they’re harder to find than I expected.
