Welcome! Quite a few people have some of the carb-withdraw symptoms you are experiencing for the firts 5-6 days. Sound like you are doing things right - my only question is are you taking a multi-vitamin? If not, I'd suggest start taking one ASAP, it could help with your dizziness. You also may want to take a look at our supplement forum, pottasium is a common thing LC'ers are low in since this diet is naturally diuretic. Just check the warnings on taking a potassium supplement if you have high blood pressure!
