It may of course be coincidental, but "Atkins flu" is a fairly well known phenomenon, it takes a finite amount of time for your body to switch from high glucose mode to utilising ketones. (It takes a lot less time to switch back, so don't weaken!)

Keep at it, keep hydrated as the others suggest, and watch your numbers also tumble.
