Diary entry: 25th May

It's about time I wrote something but it has been so long, and so much has happened that I don't really know where to start. It feels really weird writing anything at all.

First and foremost though, I need to say a huge thank you to Hannah. But like all good things, her involvement in this had to come to an end and she has moved on to bigger and better things. So goodbye and good luck. Cheese sandwiches will never taste the same again. I would never have had the courage or strength to embark on this without her and we went through a lot together. But end it has so I shall have to build on what I have achieved which, thinking about it, is a hell of a lot.

Shortly after the last diary entry we went on holiday - well I say on holiday, what I really mean is we were transported to another world. And for that time I got back a taste for living. It made me remember what I was missing. And when we got back and I got on the scales, I was genuinely thrilled to find that I had managed to gain enough to secure a stay of execution. Even better than that, the following week I had gained a further pound. I thought I was coming out of the woods and probably got a bit complacent because I haven't gained any more since then. Bugger.

Having stuck so rigidly to the terms of the contract, I can feel myself slipping again and I'm scared. But having had that taste of how much better I felt (and I can't believe it was only due to the sun, sea, sand, personal chef..... well, maybe it was) I am not going to let myself go again.

40 kg. Again. Well I suppose it is a nice round figure so it's not surprising I've plumped for it.

Sometimes I pray to cod for the veal-power to stop playing with my words but I fear it is too bread into me. For all I know, the worst may be yet to come.

I am disappointed though- even the practice nurse had written in my notes that I was 'chuffed to bits' last time I put on a pound. I guess it will go in fits and starts, but it is a bit demoralising, especially as I've just announced how well I am doing.

So it is a case of back to the drawing board or rather the meal plan, to identify the areas that had started to slip. And if all else fails I'll just down another Clinutren.
