Maybe your body was craving starches.There was this time, around the time I had just developed agoraphobia, that I developed some extremely severe hypochondria. I stopped eating almost anything except vegetables and fruits I mixed up in a blender. I also had one chicken breast per day. I completely cut salt out of my diet, and I started drinking hilariously dangerous amounts of water. Eventually, I couldn’t sleep at all, and, when I did “sleep” for a few minutes, I woke up saying “It’s the potatoes.” To this day, I don’t know what I had against those potatoes.
So, yeah. Drinking too much water - and not getting enough sodium for that matter - can be pretty bad for you. I was also tremendously fatigued, I could feel my blood pumping in my carotid arteries, and I had terrible muscle pain. It sucked.
