Metformin is a medication for people
with type 2 diabetes. But women
with PCOS are insulin resistance, and
Metformin helps with the sugar levels. I would just say to keep at it, to eating healthy and keep playing hockey. There is no best kind of exercise, but at least you are doing something. Ask your doc to see if they want you to see a nutrient to help you out. Best of luck to you, and I am sorry I wasn't able to give you the best advice, but if you find it let me know.
