My normal resting pulse is around 95-100 and that's with taking a beta blocker. I don't have a problem exercising though. I agree about the water... also, are you eating regularly? I get attacks when I don't eat. Does your dr take your BP and pulse regularly? When mine was consistently over 100, I was put on a beta blocker and that helps, but I still get episodes. I generally try to lay down and rest for a little while, drink some water, eat a little something and it usually subsides. But you definitely need to bring this to the doctor that prescribed your phen attention. Good luck.
