Hi sezzy. I didnt get that bad a cramps wheni started my cambridge diet previously, just mild discomfort. i think its due to all the crap coming out and lots of nutrients(contained in the packs) going in and our bodies adjusting. How are you feeling now?
I would suggest more water, some peppermint tea and a hot water bottle if your still having problems, try to stick with it and speak to your councelor.
hope that ur better now
