Hi,
I am not international either
but, I do have a few tips, I don't buy any of the prepackages, processed foods so I don't use the points in the WW books much either except for the ones for ingredients like chicken, veggies, rice ect....so I find the first 1/8 of the food companion book is pretty much all I use.
One of the plus sides to joining the website is that you can input all the ingredients in something and it will give you the points, it does the hard work for you. It will also do it if you have the nutritional info from the packaging. Other than that, I think you can get a lot of support on this board and its free. I would try doing it with out joining WW and if it is to frustrating, then join.
Don't get frustrated, I have a long way to go to and if we stick to it we can make it!
