I can't remember how I felt on day 3, pretty rough I suspect (SS). I'm in week 13 now, so I got through it. I think day 5 was the worst for me! I've lost 49.5lbs in 12 weeks tough! I started off a similar weight to you - I was 19st 4, I lost a couple of stone at the beginning of the year, but started CWP in August - last weigh in I was 13st 10lbs. Still got quite some way to go, but I feel so much better! Wearing size 14-16 clothes, I was 24-26 at the start of the year!!
