It's just a thought. I've experienced it myself last year - before I was diagnosed with an under-active thyroid. I thought it was just due to being a mum, working hard, being tired, feeling pulled in several directions etc. Anyway, I have spoken to several women who feel the same way. They seem resigned to it They are not old - 30's. They wouldn't dream of going to the G.P or addressing their lifestyle to try to address the problem. Do they think it is a temporary problem or are they just not bothered?
