10 weeks until my holiday

Options
It is 10 weeks today until I go to Ibiza! I've been doing Vicky Pattison's 7 day slim almost every day since February and have changed my eating dramatically. I've just bought an exercise ball and can already feel it is working, I just wondered if anyone could suggest anything else I could do? I'm trying not to care about the scales as much, I feel different/better and I think that matters the most.
