We used to have quite a few rows about me wanting a thinner duvet on and the window open throughout the year. DBH had to start wearing pyjamas because he got cold, which made him cross. Now we have a tog4 duvet and the window open, he had to give in eventually! I don't get flushes at night very often (the only time I do have them), but if I do it wakes him up so he just gave in. I know I've been let off very lightly, it could have been far worse. I had cream so rarely it was pretty obvious, so that led to cutting down on fats, and I had the advance warning about alcohol which saved many a social occasion, but I know I could have been in a dreadful state if I had no idea how to help myself.
If I am going to have a hot flush at night, it starts off with a nightmare in which I am burning to death, and I can see the red and yellow colours of the flames all around me. I can wake myself up pretty quickly and know to fling off the duvet and get out of bed, have a cold drink and walk around a bit, but I used to fling the windows wide open, I was so desperate.
