Meditating on meditating

I managed to meditate some both last night and tonight. They were only short half hour sessions and only anapana. I didn't sleep as much as I could had I not done it, but I feel totally refreshed. For now, I think if I could just manage to meditate 3 nights and 3 mornings a week, it would be consistant enough to counteract the loss of sleep. When I meditate, I think I may actually get more mental rest than sleep.
