*hugs* Definitely the caffeine withdrawal. Did you drop from a 2-liter to nothing in one day? It's a wonder you don't have a full migraine (or is that what you meant by insanely intense headache?). Caffeine is one of those things you have to go onto and off of gradually. Going back on it, if you go from nothing to a 2-liter you'll get headaches as well (although probably not the fatigue, fatigue is usually only for withdrawal). Try a cup the first day, two cups the second, etc. (You can drink caffeine-free for the other cups, if you want more soda. I'm drinking caffeine-free Dr Pepper this week, incidentally, since I was craving Dr Pepper when I picked out my soda (normally I buy a naturally caffeine-free soda, like citrus or pineapple).) And drink water! Lots of it.
Ibuprofen helps me, if I accidentally have too much caffeine. Water helps even more. Take something to take the edge off the headache, then start drinking as much water as you can hold.
I've not done any detoxes, but stomach ache and loose stools are common side effects if I eat primarily veggies for a few days in a row. It'll sort itself out on its own once you add other stuff back in. In the meantime, if you can eat a high-fiber veggie, that might help a little bit.
