I'm starting CD on 29th June and I have several activities planned (joys of finally being 18!) My friends and I are planning to go clubbing and I was wondering whether some of you have. I was thinking of having a shake before and drinking water throughout the night, but was worried about light headedness. I've decided that I want to fit CD into my life as much as possible, rather than feeling like I am a prisoner of the diet. I hope that makes sense, so I would just like your input.
