Endocrinologist

I saw the endocrinologist last week.  She said my blood work was not too abnormal, which did not indicate whether or not I had PCOS.  I do have other symptoms.  I did get my period for the first time on tamoxifen the week before so the blood test results could be a little off.  I hadn't had it since April, while on the chemo.  She gave me a Rx for metformin and told me to come back in a month.  She also wants me to start a diet like South Beach again.  I was successful on it before.  I figured I would start the meds tomorrow.  I have to try to figure out how to be on South Beach and not have artificial sweeteners.
