I have been on oestrogen implants for 27 years and intend to keep having them for the rest of my life. I am almost 67 now and my bone density is that of a 50 year old. My mother SUFFERED from osteoporosis and HRT has allowed me to avoid that, plus life without oestrogen is a nightmare of flushes, panic attacks etc. I have tried all types of oestrogen replacement but implants work for me. I only have to think about it twice a year, the dose is tiny and avoids the first pass through the liver, allowing me to get on with my life.
If your doctor is refusing to prescribe HRT then I suggest you either ask to be referred to a menopause clinic or find a new doctor who is more sympathetic.
Good luck, a decent night's sleep make such a difference to your life Adnil1949, hope you get one soon.
