Hi vixjean! That thread that Jane linked to will probably answer all your questions for sure. But if you have any others feel free to come back and ask away
I think generally the choice you'd have to make is whether you're completely sick of counting or not. Because one of the great things about WW is that you have two choices -- you can go on Core and not count anything (but stick to a list of foods) or you can go on Flex (and count all day, but smaller numbers than cals). Both plans give you the flexibility you're looking for (both Flex and Core give you a bank of 35 weekly points to allocate as you wish).
Good luck, vix!
