Nemesis Reborn. Im scared.

Right guys, basically at alton towers, i have ridden galactica and i love every bit of it. But im still concerned on nemesis reborn. I have a fear of rollercoasters but i know when i get off I will have loved it. But i just dont have the balls to do it. So people that have ridden Nemesis Reborn can you explain how every part of the ride feels since I know the layout perfectly but dont know what to expect! Also the label ‘The worlds most intense ride experience’ makes me worry even more! Thank you.
