Boy, you are right on that, DougR. As I said I took some over this last weekend, started at 60mg, then stepped down to get to just 5mg, yesterday. One of the side effects can be congestive heart failure in persons predisposed. Well, by yesterday, I was having a hard time breathing with any kind of exercise, couldn't lie down without feeling like I couldn't breath. In short, I had all of the symptoms, on top of a leaky heart valve, and that was with my oxygen! That's the first time it has caused such a fast and dramatic change. Don't know why the docs insist on prescribing such things when they know one's medical history. I am happy to say I feel much better today and am over being scared! Sheesh! It's enough to make a person totally renounce Western medicine!
