This has gotten interesting and a little bit complicated. Yesterday after getting a cup of tea to stop myself fainting I remembered I had an event. And Events equal cocktails and canapés. Thankfully none of the canapés were sweet, but the cocktails, I assume, were. I am not sure if they break the diet or not as I cannot remember them being on the no list, but I am smart enough to know I probably shouldn’t have. I had two but they were small and they did not put sugar in. It is a slip but I am hoping not a big one.

I go to the Sure Improve Rooms with my friend, Mail on Sunday journalist Holly Thomas, and she is amazed that I have managed three days on a no sugar diet. It is not fun at the moment to be honest, I have a constant, awful, headaches, I have no energy and I am craving cake and chocolate. On the way back Holly and I check out our goody bags. “If there is chocolate in here I am going to kill myself.” I tell Holly dramatically. There is, but by some joyous miracle, it is Green & Blacks dark chocolate. On week one I am allowed dark chocolate. I am so happy I actually hug Holly. Before the event I was busy so I grabbed a Sainsburys Meal Deal for lunch. I usually get a coke with this. I look at if longingly but with pride I grab a bottle of water, yes, water! I almost cannot believe myself. Who knew I had this willpower?

Today I went into London and I saw tea shops, constant coca cola signs and people with the cans or bottles on their hand. I have lunch in Pret and they have fizzy juice. I really want a San Pellegrino, chocolate or cake but I don’t break. We are constantly bombarded with images for foods full of sugar and salt that are terrible for us. In the house it is easier but there are the headaches and the weakness to contend with. This is not easy but I have noticed I am already less bloated just four days in and my cravings are being replaced with something stronger and greater: determination.
