Mine was 8.4 a couple of years ago. I was put on to Atorvastatin. That one was insidious, but after a 6 months I was feeling generally slightly shit (tiredness and muscle weakness) so I stopped it. For other reasons I then went on to a pretty determined 5 a day regime. A few months ago after 6 months on loads of fruit and veg my result was 6.3. Still too high says the quack and persuaded me to try Simvastatin. That gave me rotten gut cramps within days. When I finally confessed I had stopped it, another test showed I was back up to 7.2. So now I am on a fibrate. The jury is still out on that. I'm giving plant sterols a try as well now.
As I said to my GP. it's a question of quality of life, not just length.
