Thanks for the help, they sound like sensible suggestions and definately things that I can put into practice.

I work in technical support for a software company so I often work late to support the US market so my mealtimes are a bit strange sometimes. I am now starting to try and eat at more sensible times and will try and implement your suggestions. It seems that the general consensus is to eat before and then only if needed have a snack at home.

Thanks again!
