Hi Ciara,
I'm in the first week too, and know what your going through - but your doing much better on me with the water, I'm struggling with that, I found that I struggled a bit with day 5 but I think that was purely cause I worked from home, and its my place of weakness !! But am surprised have not actually been hungry - guess its just a habit now to eat as and when I'm bored etc. Sounds like your doing brill, well done,
K
