Caffeine withdrawal?

I don't think I've gone through a full-on caffeine withdrawal, but when I go without drinking soda I sort of get sick. The past few months I've tried to start drinking soda less and less, every other day at the least. I started doing this because there would be times I would go a day without soda and by the afternoon I'd have a horrible migraine and nausea. The only thing I could do to get rid of it was take some Aleve, have a soda, and go to sleep. When I woke up the migraine would be gone and I'd feel much better. Getting that way really started to annoy me so I decided I'd try to be a bit healthier and not drink soda so often. It's definitely hard because I really do love soda and it can be such a refreshing drink to have. I think I do pretty well and I've gone down to having it every few days or every other day. It's nothing major, but it's still a start for me.

i just wrote a post abt coffee! lol i actually dont experience withdrawals at all, not sure why because i do drink quite a bit. but i rarely if ever get a caffeine headache, and on weekends i usually go coffee-free, unless im going out with friends or something
