Thanks for the advice to switch from Norvasc (10mg) to Irbersarten (Avapro) 150mg. We talked about the "lead legs" during running that might be caused by Norvasc.
I have been on the new med 2 weeks ago, and I cut a whole minute off my 5k time, 23:30.
Hey, that's good news! Thanks for letting me know. I'm off running at the moment, twisted my foot badly the other night, its a lovely shade of purple - be a week or so before I'm back in the race!
