Turns out that I may be remembering that I craved ice water on lithium. I developed this weird thing where my body wasn't holding onto electrolytes and instead I just peed these incredible amounts, all the time. Worse than just lithium. Craving ice water goes with that.

But I have found it helps nausea. When I've had toxicity or taken meds and then gotten really nauseous with a virus or something and am trying to let them digest I've just eaten crushed ice and it helps me.
