I took on menopause without knowing how it affected other women in my family (no-one left to ask) and that is often the biggest indicator of how you will go. While I didn't have the hot flushes during the day, I never found it a gradual ride - the symptoms came on quite suddenly, but I was also carrying a lot of stress and anxiety, and sleeping poorly. Unfolding myself from a sitting position in the car was excruciating and I would feel like an old woman for the first few steps. Loss of libido and shocking headaches came with it, too. (Anything sound familiar?) So far on Letrozole, I don't think I have any side effects that are noticeable, except for the hot flushes and that the night sweats are back, but I might think differently if I hadn't gone through menopause first as I suspect that I never went back to my base line normal. I think that I probably just got used to things, particularly with the bc diagnosis to take on board. I don't know if this helps or not.
A couple of years ago, I did read a book (written and published in SA, I think) that was a collection of stories about different women's experiences of menopause. What it did do, was highlight the range of symptoms and severity that is experienced. And just how little is known or recognised about this stage of life. I've done a quick google and I'm pretty sure that the book is "Menopause: women tell their stories" by Debra Vinecombe.
For me, the rage is definitely simmering, and the anxiety is waiting patiently at the door for a chance to be let back in. Is this Letrozole induced, menopause or just life? One of the things I am determined to do (famous last words) is to not let that stress build again. I'm not sure how I'm going to prevent it but I'm going to give it my best shot.
