ANY soda is bad for health. I've known several people who never liked it and never drink it. I LOVE diet Pepsi and would guzzle it by the 2-liter bottle if I could. But it's really bad, so I won't.Yes, I hear diet drinks are bad for you and I will give them up soon. I've been drinking Tab's and diet coke for over 60 years and they have not killed me yet.
