I was happy to see your post, as I know that SBD has been helpful to many with PCOS. I suspect that I have it as well (I'm currently awaiting results of tests to see for sure), and my OB/GYN told me that she would recommend doing SBD as a way to deal with the effects of PCOS. That was great to hear as I'd been doing it for several months when I saw her.
There is a PCOS support forum here on the boards, and it's great. Check it out if you have time.
Congrats on your recent marriage! That's great! Like you, I have a lot to lose, and am planning to do it for good this time...SBD has really made that possible. This is the longest I have actually followed a plan in my life. I am thrilled at the ease of this WOE and know it is something I can continue doing forever.
I hope you'll feel the same way!
Be aware that depending on how much sugar and high glycemic-index carbs you've been eating, you will have about 3-5 days of detox in Phase 1. It can be pretty awful, with headaches, feeling tired and cranky, and craving madly. Don't give in to those cravings (no cheating in Phase 1 or you really need to start over), and you will be amazed at how great you feel!
Welcome and enjoy!
