Hi Afrohead, and
We have a "PCOS" area in the "Dieting with Obstacles" forum - there are many folks on here with PCOS, so you can get some great advice.
If you had good luck on a lower-carb approach, maybe something like South Beach would work well for you? It includes some low-glycemic carbs (more than Atkins), which might help with the lethargy.
Anyway, can't wait to get to know you better - keep posting!
