Are you dehydrated i.e., not drinking enough water? I saw your note about metformin and topamax. If i get dehydrated it really does tire me out. I am not a water gulper but sometimes i do and i surprise myself. Im like oops must have been skipping my water!

Oops i read that as your lower blood pressure number being 67, not your pulse. I dont see anything wrong with your pulse rate. But people usyally report blood pressure as a pair of numbers, x over y - systolic over diastolic. 129 by itself is hard to interpret, if not impossible.
