I have pcos and manage to lose sixty pds with diet, walking and birth control and biotin. After miscarriage at the three month mark I had over indulged and gain back all the pounds plus fifteen. I have restarted birth control and biotin and occasionally I take the metformin. However the three mixed together makes me nauseous, tired and light headed. My problem is my ankles have started to swell, my knees are aching and I feel constantly swollen, all over. Like walking in a puff. My left eye has a tendency to bulge and pulsate. It s hard to get out of bed at 215 pds 5 2. I m constantly in a state of drowsiness or bottomless hunger. Please help.
