I'm on Cardizem LA. I was on just a diuretic but then my bp went further up so they switched me to cardizem which is a calcium channel blocker. My bp used to be around 190 over 105 now its around 152/88. Unfortunately, this woe has not reduced my bp yet after 7 weeks. They say it can take months. I think mine is genetic because I wasn't that overweight. (relatively speaking) I did lose 11 pounds so far and weigh 141. So I believe you can lose weight. Doesn't seem all that much slower than most people here, considering I don't have that much to lose, which makes it go slower any way!
