Hi Chalkie86
I too feel tired all the time and this has been going on since i was about 23 (i'm now 30). My boyfriend's mum used to say 'i've never met someone so young who sleeps as much as you do' when i first met her.
Didn't realise i had PCOS until summer 2010.
I am quite active and have been regurlary exercising since spring 2009 3-4 times a week. I started off feeling better for the exercise but recently i haven't been able to do as much as i have been feeling exhausted, extremley dizzy and suffering severe wind which is embarrasing. It is SO annoying as i really enjoy keeping fit.
Just want you to know you are not alone and if you ever want to chat just PM me.
