Scatty, poor you. The first week can be difficult as your body is withdrawing from all the card/sugar and nasties. It is releasing it's toxins and adjusting to being on LT. You will feel tired, light headed, headachey, disorientated, moody, weepy and just generally awful!
I think most people find the shakes hard to stomach at first. I know I did, until I found a LT slush puppy! I put ice in the blender and crush it, I then add ice cold water from the fridge, add the powder and mix it together, et viola - a LT slush puppy! They are delicious, and I love them. Add coffee/peppermint tea/sweetener to your shakes (that's if you like those things) to try to spice them up a bit.
The water also has to be freezing cold to enjoy, add some ice cubes.
Believe me it does get so much easier once ketosis kicks in! In a week or two the initial yuckiness will be a distant memory. The high you get from your first weigh in will spur you on so much, and feel you full of determination, then nothing will stop you reaching your goal!
