If you get overly worked up or frustraited, this also happens. Using Ki may effect your mood. You may have mood swings, but I doubt it. It's somewhat unlikely, I've seen it in a few friends, and maybe once or twice in myself.
You don't really have to worry about the mood swings, but if you do have them, try meditation or you may be trying too hard to work on your Ki.
