Sleep (rest), water, vitamins, nutrition (getting the best you can get), minimizing stress, these are the things that will make the biggest change for you. Keep staying the course and remember just because the scale isn't going down doesn't mean there aren't major changes happening in your body. Stay the course. I'm a PCOS patient too, so keep those carbs really low and what carbs you do get make sure they are higher fiber, low carb options. Limit fruit to very little if not eliminating it altogether for now.
I echo one of your previous responders on following your surgeon's plan. One thing my doctor had to remind me of is that I am no longer a normal eater. My new stomach requires me to eat 3 meals and 2 snacks a day; otherwise, you will never get your proper nutrition in. Focus on clean eating, and getting your protein and good fats. You will find that the scale will continue to decrease.
I am at 3 months now, and losing just shy of 2 lbs a week (on average--some weeks the scale reflects nothing, then by the end of the month, it balances out to almost 2 lbs a week). Considering we have PCOS, that is some AWESOME success. Remember insulin resistance requires us to keep our carbs low. Just keep in mind that with every effort, you are gaining control of that runaway train that couldn't be controlled by anything else other than weight loss that used to be virtually impossible. With every pound lost, you are closer and closer to your body working more typically with PCOS being further and further in the rearview mirror! I can't wait to tell that b*tch GOODBYE forever! I am sure you feel the same way.
