I want to throw something into the mix - I'm on a roll here 

I happen to have a 'Personal liquor License' because of the work I do.  When I went on the course for this license we didn't just learn about the dangers of alcohol but also the benefits!!! Something that is rarely advertised! 
Of course drinking alcohol depends on various health issues but after a certain age e.g. 50 a small amount has been shown to help prevent heart disease, stroke, some cancers and dementia - to name but a few.  When you are suffering from hot flushes etc we are advised to avoid alcohol, so HRT can enable us to enjoy just 'a little of what we fancy' which may do us good.
In my workplace so many mature women I speak to tell me that they can't drink alcohol anymore because they get headaches etc. - I'm convinced it's the lack of oestrogen.
I certainly don't drink very much - probably only 1-2 units per week at most - but I do so in the knowledge it will do me more good than harm.  
Now 57, I am coming off HRT soon and am dreading the headaches, flushes etc. but hope that at least I may have delayed the onset of osteoporosis,( my mother has lost 3' in height) and reduced my risk of heart disease and some cancers while I was taking the HRT. The HRT has also enabled me to drink that little bit of alcohol that may also benefit my health in future and I doubt I'll be able to drink when I'm off the HRT.
HRT has helped me to cope with some really tough times over the last 18 years - yes,I've been on it most of this time - and I will certainly go back on if things get bad again.
