Yes it can be...knew I had a real problem when I started throwing things (true) Tried HRT which made things worse...remember your moody teenage years? well multiply by 10! Finally was recommended natural progestogen cream by a friend and I now am back to the quasi normality that is me. Now I am NOT suggesting that it will suit everyone or that you should rush out and get some but it is worth considering and getting more info on. Try looking on some of the many menopause advice websites, you can also google on "natural progestogen" please note that I make no claims for its suitability, safety or efficacy and I have no connection with any retailer apart from being a customer.
