I need a kick up the backside!!

I went along to my Slimming World group this morning to find that for the third week in a row I had stayed at the same weight! I started this years weight loss programme on January 6th & did well for the first few weeks, but seem to have lost momentum!! Two rounds of birthday cake & the accompanying festivities haven't helped - not to mention the Valentines day gift from my Hubby of what looked like my bodyweight in Maltesers!! So, I really do need a kick up the backside if I'm to achieve my first target of two stone off for my holiday in May, ten weeks away now & only seven pounds down!! I'm going to sign off now & get on the treadmill for a half hours power walking!!!
