Hey Patty,
That's what I worried with when I thought about a diet aide. When I had all of the weight on I had high blood pressure and was worried about how that would affect my heart. But since I've lost the 38 pounds my blood pressure is back to normal and I'm off my med. So I felt safe to try the diet pill now. I'm going to start the full dose today. They said to start with a half dose to see how you react at first.
