Thank you ... that's an idea. Just seeing articles suggesting the currently recommended dose might even be an over-treatment.

I've also been seeing that the irregular heart beat risk can be more of an issue with a leaky heart valves (which I have but is mild and supposedly quite common... apparently many have it and don't even know)...another reason for a smaller dose perhaps. So wish there was more data on all this.

I can imagine this doctor saying with irritation that if he thought a lower dose would have been better he'd have suggested it in the first place... unlike some who would be up for discussing it. But something to keep in mind! Am curious if you look into it or do it how that will turn out...!
