I'm back at SW. I have been saintly for 3 full weeks. First weigh in - 2.5lbs on. Consultant checked my totally accurate and truthful diary - and I'd done it all right. Also exercised hard 6 out of 7 days (have to have a rest day)!! Second weigh in - 5lbs OFF - woo hoo, off I go I thought!! Last week - 3.5lbs ON. No sense to me. Have now had 2 BAD days not on plan and will therefore have gained again (but at least deserve it). :break_diet: Gone back to it today - plan to try hard for the rest of the week and hope for damage limitation by monday evening weigh in. BUT what the hell is going on??? I have at least managed to stick to exercising - thank goodness - but I am despairing I really am.:4633: (this is me just digging a hole and crawling into it - not going to bed!) HELP!
