Well almost everyone blacks out, the ride is designed to do that.
Well, I know the Senior Lead at Goliath and he knows a bit about the ride. He says, it's not designed to make people black out, and almost no one blacks out on it. Yup, looks like you have issues!
Well everyone on the ride that got off with us did, and my 2 friends i was with rode it twice more, and everyone that rode with them on both of those rides did too. I waited for them at the exit while they rode the last two times and heard several people talking about it happening to them as they exited.
I'm not talking about full-fledged passing out unconscious, I just mean that the G's are causing your vision to go white. For me it took me like right to the edge where I almost couldn't see at all and then it levelled out.
