"I just found I was starting to get affected by hangovers badly. You know how people get hangover blues? I just started to not cope with them well, anxiety-wise, to the point where I was being really horrible. I loved going out and getting pissed, the being drunk wasn't the problem because I was never aggressive, I think I did take it a bit too far. Drinking was my vice, but I can honestly say I'm happier without it."

Harry's fiancee, former-Escala violinist Izzy Johnston, is also alcohol free, and he believes it is the best thing for both of them. He tells Attitude magazine:

"Izzy doesn't drink either, so it's ideal for her. It just means you want to leave the party at 1am, rather than not want to leave the party at all."
