Thanks hamster,

I take nuun electrolyte tablets right now, and drink coconut water. I thought dehydration might be a factor too, but I started with the electrolyte tablets because of bikram yoga and the excessive sweating. But it hasn't improved at all. But I do wonder because you need such a large amount of water on lithium, then with the hot yoga, maybe it still isn't enough?

I get a mix of migraines, ice pick headaches, and cluster headaches along with tension headaches. It really sucks. I'll look into the electrolytes you mentioned tho and compare them to the nuun tablets I'm using, maybe they would work better.

Thanks for all that info.

I just looked at mine and saw sorbitol I've read that can cause headaches, but I'm not sure.
