I lost 3 stone on CD last year and have gained 1 1/2 of it back and am in a state of panic about it. I can't afford to do CD again and was wondering about doing SF. I've got to do something different before I gain the whole 3 stone back. Has anyone lost a stone and a half and how long did it take? Also do you feel really hungry when doing SF? Hope someone out there can give me some hope!
