I have a friend with OCD who works for the NHS. It takes him at least an hour every night to go through his routine of checks etc before he can go to bed.I have OCD, if that counts. Not to the point where I have weird habits like turning the light on and off so many times before leaving the room, but silly things annoy me. For example, if I notice that a drawer is left ajar slightly, I have to get up and close it. I try to ignore it, but genuinely can't relax until it's closed.
