I have it as well.
I was diagnosed with ovarian cysts 4 years ago, I had pain and very heavy periods, but no other symptoms. Then, about 2 years ago I started gaining weight for no reason, breakouts all over, hair growth all over... a real nightmare. I went to my Dr and asked for the pill. She put me on it and it was great for about 7 months. My periods were less heavy, my face cleared up. However, 7 months after my period stopped.. I didn't have it for 6 months or even more, I don't really remember now but it was a long time. So my Dr started testing my hormones, testosterone was high, she sent me to the endocrinologist. She diagnosed me with PCOS, and in addition to the pill she gave me metformin. It gave me really bad stomachaches and nausea but I discovered it's better when I take it with dinner. Almost a year later, I lost about 15 lbs or so (I wasnt overweight, I was about 130-135lbs and now I'm 118 which I was before this all started). She also started me on spironolactone few months ago to help with hirsutism. I have check-ups every 3 months, they do a blood test (to make sure potassium levels are regular, because of metformin and spiro). Everything was great, my period returned etc. but when I went to my last visit, my endocrinologist was on a maternity leave so someone else saw me and she said since I lost so much (um, ok, it's not that much) weight, my PCOS is probably gone and I don't need to take metformin anymore. This really sounds dumb to me, because weight doesn't cause PCOS, it's the other way around. Or at least that's how it was in my case. So I stopped, and I'll see if I stop having my periods or start gaining weight I'll ask to go back on it.
It really sucks, there's nothing we can do about it to get rid of it once and for all. I'm also scared I won't be able to get pregnant once I come to that point in my life.
