Propranolol and rollercoasters

Just wondering if anyone who has been on this medication has been on rollercoasters?
I've been taking it for about 4 weeks now, and most of my fears regarding this medication have subsided. I've gotten used to my heart being in the 50's a lot of the time, and I've even drank alcohol since and felt fine.
But I'm going to Orlando in September and doing theme parks. I do that every year. I love rollercoasters! I'm not too worried about it dropping my blood pressure. My blood pressure is always in the normal range, it's not low on this medication.
But I'm curious if I go on an adrenaline based ride, and this medication blocks my adrenaline, how the body feels in that situation.
So I'm just wondering if anyone has done rollercoasters on this medication.
