Bystolic (Nebivolol)

Today, my cardio switched me from 25 mg metoprolol twice daily to 5 mg
Bystolic (Nebivolol), I think it's 2x daily (need to ask to make
certain). From what he told me and from what I can figure out from the
wikipedia entry, this beta blocker doesn't have the same negative
effect on VO2max that metoprolol. Anyone else have any experience with
Bystolic?

thanks,
