I switched. Here's how: I was training martial arts like crazy at the time, after work 5 days a week. I wanted to compete in a tournament. To qualify I had to attend 'special' classes early in the morning. They started 6:30AM, and that meant a 5:30AM wakeup for me. So I set an alarm and did the first morning. I put the alarm in the next room, so I'd be forced to get up and turn it off. Going out in the dark felt as weird as going out without any pants on. I was convinced no one else would turn up for the training. They all did, of course. I did this 5 days the first week, and spent all day at work half-asleep at my desk. By the end of the following week I felt normal, and it's been my routine ever since, tho I'm not training any more. I'm still not a 'genuine' morning person. I can't maintain a conversation before 7AM, but I am productive. Speaking of being more productive: if I head to work at 6AM, the couple hours I get of no interruptions are guaranteed to be the most productive in my day.
