I did 30 minutes on my minibike last night and didnt even get out of breath. On my former beta blocker, 20 minutes would do me in. I have been on the new one for over one month now and havent much exercised. Just FEEL like a weight has been lifted over this month. This is EXTREMELY hopeful. I am feeling like i could be normal, instead of having all these ridiculous obstacles stacked against me. Which - i am hearing it - sounds like my childhood carried over into adulthood.
