I have Mitral Valve Prolapse, grade 1, and have been taking Propranolol 40 mg for more than five years now. From what I know, it is not a serious issue and affects quite a large number of people. I want to start exercising and have got creatine; I used it some time back for about a month, when I used to use 5 mg an hour before exercising, but I didn't take it each day, so I can't say I have loaded on it.

Now I want to load, and would like to ask if an excess amount can affect the heart condition that I have.
