Negative for Cushings

The doctor FINALLY called me after one week of waiting on test results. My blood cortisol levels were normal and the 24hr urine free cortisol was normal. The Endocrinologist is wanting to put me on Metformin to assist the weight gain and fatigue. I took Metformin earlier in the year when I switch to a new general practitioner, she prescribed it for PCOS. I took it from Feb to April but the side effects were so inconvenient I stopped. I have been doing my research and it appears there is an extended release version that has less severe side effects. I asked if they could prescribe that instead, we will see..... Hypothyroidism and polycystic ovarian syndrome, thats my life. ::sigh::
