Calcium Channel Blocker usage?

Disclaimer: I am in consultation with a Cardiovascular specialist who specializes in athletes. HE recommended I talk to other athletes who take or have taken them.

I currently take the smallest dose of an ACE inhibitor and a a Beta a Blocker. A CCB may add some benefits over the ACE with regard to exercise induced hypertension, but, he worries it may make me lethargic.

What have your experiences been? Feel free to PM.
