Hi Laura,
Cohens certainly works but it is very strict. I lost 35 kgs in just 4 months so you should be able to reach your
goal weight in no time at all. It is so encouraging as you seem to go down a size in clothes evey few weeks which really keeps you motivated. The first week or 2 are the hardest and if you just keep reminding yourself that it does get easier and if you can just hang on through those first difficult days you'll reap the benefits of Cohens. Sorry I don't know anything about PCOS, but I'm sure its not going to hurt to give it a try.
Good luck and I look forward to hearing how you go.
Take care
Beck
