I think it depends on a number of things. Are you strong willed enough to have a syn splurge at the weekend and then get right back on plan come Monday? Or would it be a slippery slope to going completely off track? When is your weigh in? It may not be a great idea to bust your gut on the sunday if weigh in is Monday. But as said, you're already losing really well at 2lb a week, althugh this will likely decrease at some point. So why change what is so obvisouly working for you
