I had a long reply to your previous comment written out but you deleted before I could post and it got lost. But I guess what I was saying does boil down to this. I don't have a great deal of faith in the shallow, one size fits all, drug based approach I was offered. I do intend to look at wider options, and you're right that there's a lot of information available. However, I don't intend to do a Steve Jobs. If it looks like I've sustained damage to my arteries already or I can't find an intervention that works then I'll revert to the suggested route.
