Coaster lovers! HELP! Intimidator 305?

I have ridden Apollos Chariot, the Griffon, and Alpengeist at Busch Gardens Williamsburg in Virginia. My favorite coaster is Apollos Chariot. I am going to Kings Dominion next week and I want to ride Intimidator 305, but I have heard a lot of comments from both my family and friends that have ridden it that they passed out on the ride or they blacked out. Is this true? Is this ride anything like Apollos Chariot? If I've ridden the rides at Busch Gardens, can I ride this coaster or is it too intense for me and my health? Note: I almost blacked out on Alpengeist... is it more intense than that coaster? I think I'm scared to go on Intimidator....you could say I'm intimidated! Please help.
