@MoiraC I've been chatting about acupuncture on a couple of other threads here. Clinical studies have shown it has no effect on hot flushes (my oncologist looked it up for me when I enquired). She did mention that some might have a placebo effect, and if that was the case then good! Some of the women here have reported it helps while others have said not at all. I say give it a go and if it works for you, fantastic! I'll be interested to hear how you go.
Definitely will ask the GP about melatonin.
