Headaches are often caused by carb and/or caffeine withdrawal, but I'd think you'd be over them by now.

It helps if you post what you've been eating/drinking so members can get an idea what you might be doing right or wrong!

Have you found Fitday yet? http://www.fitday.com/WebFit/Index.html It' free...and it lets you record what you've eaten and you can keep track of the carbs, fats and proteins. You can also post a link to your fitday account so you don't have to copy and paste everything on here!

Good luck! Post what you've been eating....and maybe someone can figure it out.
