Hi...I'm new here and I have a question....

I'm only on day 4 and doing pretty well (no cheating/4 lbs gone !)
but I seem to be having a constant headache. Nothing bad...just a constant dull one. Could this be sugar withdrawal ? I've not completely let go of the caffein yet, so its not that. Maybe just allergies and not realated at all to the diet.

Anyone experience anything similar or have any suggestions.

Thanks
Deb
