I took a long break from SW as I got too complacent on it and the weight wasn't shifting as I wasn't doing it properly so I went onto Slimfast for a few months for a break. Which worked. Now here's my dilemma: I am ready to go back on SW and am really looking forward to doing it again. I have used up all my Slimfast stuff and will be restocking my cupboards with free food but WI is on Wednesday and I don't know how changing part way through the week will affect the WI. I think I put on a couple of pounds anyway cus I had a party at the weekend so should I wait til after WI to change or change now?
