I don't have this, but I do have some input for you, and especially if you want a more "normal" sleep-wake cycle.
For most of us, the natural cycles of day and night regulate our circadian rhythms. Most of us get tired a few hours after sunset, and awaken spontaneously once it's light. The pineal gland, which responds to light, and the sleep hormone melatonin are involved.
Those with circadian rhythm disorders may not respond to light and darkness the way most people do.
If you want to be active during the day and sleep at night, the single most important thing you can do is set and keep a consistent wake time. My suggestion would be to set this and keep this consistent every day. By getting up at the same time, you are re-synchronizing your biological clock, which controls your circadian rhythm.
Upon arising, immediately expose yourself to bright light. Indirect sunlight, because of it's natural full spectrum is best.
Also have a consistent bed time. Your mind and body will adjust to this and you will then be more in control of your sleep-wake cycle.
Doing this is no more difficult than adjusting to jet lag, which thousands of people do every day.
