Congratulations! It's hard but you can do it! After your body adjusts with what they call Ketosis it is supposed to get easier. There are many ways to do Cambridge successfully. SS is only one of the ways. An all or nothing attitude can be the greatest asset in doing SS or be the downfall of many. In my opinion the key to success is inner strength - Have it in yourself to pull yourself up if there is a momentary lapse and be prepared for it even though it might not happen in your case. Never be too hard on yourself! It truly is all about mindset. I hope I can join you soon as soon as I get my medical issues out of the way. Best Wishes
