You have not mentioned what you have tried so far. However, I was getting hot flashes and tried many things unsuccessfully. But, since I started taking "starflower Oil" immediately I noticed the difference. Also, about tiredness and mood swings - I consulted a homeopathic Dr who recommended - I think it is called Phosphorus (Phos.). Two tiny tablets and I am fine next day! I know it could be a damn nuisance - what worked for me may not work for you! Don't stop trying. Good luck.
