Just When I Was Feeling Proud of Myself...

I have spent the last two months dieting, and, even if I say so myself, I've done rather well. I've lost over a stone and a half simply by eating low fat foods, eating lots of fruit and drinking lots of water. I've cut out all the junk - no crisps (painful), no fizzy drinks (very painful), no cakes and biscuits (don't ask) and worst of all no chocolate. As you can tell, I have rather a sweet tooth. To go without a Mars Bar or a Kit Kat for two months is something no one should have to go through. But today has seen all the good work undone. My American mate, who I'm spending the weekend with, in, well, you'll just have to wait, has so far today forced me to eat a Ham Omlette with chips for breakfast, a Beef Kebab with chips for lunch and now wants me to go for a Mexican. Can someone rescue me please? I have (or had!) lost four inches of my waistline and have had to insert two more knotches into my belt. I can't go back. HEEELLLPPP!
