welcome rachel

For me a couple of thing really motivate me. I have PCOS too and every time I am tempted to eat something carby, I remind myself that I am doing this for my health and so I can have a baby.(hopefully!)

the second thing that motivates me is that I feel fantastic!!!! once u get over the first 2 weeks or so, you will have loads more energy and will feel much more alive. For me too, it helped to improve my moods.

the other thing is that once you get into the plan, if you do eat something really off the plan, it will make you feel terrible - I get hangovers from popcorn!!!!! so this really makes you think before you eat....e.g 'Have I got time tomorrow for a really bad hangover, and feeling generally crappy?'

the last thing is that losing weight, getting compliments from people and being able to buy nicer clothes etc, are great motivators.
I will admit that it's really hard at the beginning but once u get into it, you will delighted!!!

good luck and let us know how u are getting on!
