Hiya!
Ok firstly, why are you having problems with the water?? Go to your local garage and buy a 1 litre sports bottle of water.. carry it with you every where and just sip it throughout the day, I find im drinking atleast 3 litres of water this way!
And secondly, unless you have had something outside of the diet plan you wont be hungry.. its your physicological hunger.. We all experience it.. its the weekend, a time for munching and enjoying a relaxing weekend, but remember healthy food will be there once you have reached your goal.. it is a short period out of your life, how ever long it feels right now.. but the results are speaking for themselves and you will feel amazing for getting through it!
Go have a nice hot bath/shower. Was your hair and rinse it a few times with conditioner to make it feel extra soft! moisturise your face and give yourself a good pampering.. Paint your nails and toenails, and before you know it will be bed time..
Good luck xxxx
