Try only drinking water. Just try it for a week, I guarantee that you'll feel better.

I still have my one cup of coffee every day, other than that, I've completely dropped soda (I was having migraines due to too much caffeine and not enough water). The amount of things that it has improved is actually pretty insane. Not nearly as much inflammation, my hand is steady, a bunch of other things I don't really care to disclose lol but I think you'd be really surprised.
