Hi Dippy,
I can't offer any more advice than Viv. I think we're going down the same route as you though.
On reading the link in the OP I'm very concerned. I just know that the talk of anything CVD related will mean our (fairly useless GP) putting my husband on Statins again. He stopped taking the Statins in the first place because of the almost instant ED they produced. He had taken six pills, one per day at night, and all libido and possibility of an erection disappeared. So he stopped taking them and a few days later he was good to go. Not being totally sure if the Statins were the cause he tried taking them again and within a week the same thing had happened so he stopped taking them and hasn't taken them since. The GP does not believe that Statins are the cause - she says 'Statins have no undesired side effects'
However, although my husband has function now, he has lost all desire. We have no idea what's causing this; could be his age (nearly 50) could be stress, although he says he isn't stressed, could be his diabetes although the GP says not - it was caught too quickly. Could it be the Metformin? GP says no, but by now we have no confidence in her opinions of prescribed drugs.
We are going to see her again next Friday, but neither of us is very confident. Sadly, there is no male GP at our surgery.
