Yes I think a one month mini challenge would be a good idea...
Re- PCOS- your doctor can probably refer you to a nutritionist to help make a plan that is suitable. In the meantime it can't hurt to read up on PCOS and seek's menu looks pretty good even if you are just trying to reduce your sugar intake or do lower-carb. I am currently doing a lower carb version of Weight Watchers and it is amazing how many "hidden sugars" you find in food products
I have found that by watching my sugar intake and eating wholegrain bread products such as bread, high fibre cereal, whole wheat pastas and brown rice that I am losing weight and feeling a lot healthier. I find that white flour products and processed food (dougnuts, packaged cookies etc.) give me headaches or make me feel sleepy and unfocused at work. Suprisingly once you stop eating these things for a while I find I don't miss them and don't crave them anymore.
There are several different plans out there like Sugar Busters, plans for diabetics, South Beach Diet and I have also seen books on the glycemic index. Check out your local library and do some research to see what is a good fit for you.
Also here is a page from one of my menus - it runs along the same line as seeks except I have one daily coffee with real cream and real sugar - must have it!
