Has anyone else had this? I weighed myself the day I started sw and since then, first thing in the morning I weigh myself at home. I have lost 9lb on my scales but on sw ones I have only lost 4.5lb (maybe more when I get weighed later) has anyone else had this? its disheartening to lose 3 pounds on your scales at home to then go to group and find you lost 1lb (officially)
