LOL Im with ya cyster!!
I eat ***** flakes for breakfast every morning....the only thing that is different between you and I is that I dont get AF - so my mood swings just come and go when they want to...
Needless to say, I am up right now, because i am sooo mad at DH and I dont feel like sleeping next to him right now in fear that i will smack him or something LOL

And the worst part is, that it was something stupid that we got into a fight about, but I am too mad and stubborn to apologize
I dont know if there is anything to control it, but it IS a symptom of PCOS - so you are defintely NOT alone!
