Hi Katie! Good luck with your weight loss and health.
I'm only in my second week of PB and just getting through the 'low carb flu' headaches and lightheadedness as my body adjusts.
I've been haunting the forums since I discovered Mark's Daily Apple, I'm almost obsessed - I'd read bits about carbs before but never really managed to put it into practice. So having a 'plan' and a supportive network is brilliant.
