Can pcos give you mood swings?

I was recently diagnosed with PCOS (polycystic ovarian syndrome) and I was wondering if anyone else notices mood swings worse than other days? Mostly pissed off and upset. On those days I also feel like I'm about to eat my whole fridge, but thankfully I stocked up on healthy food, so it isn't too bad. I've been having a hard time dealin with this, reading online isn't always correct. I just wanted get some other opinions.
