response: You ever had any sleep inversion issues? Like reversing your normal sleeping tendencies.
history: I sometimes have trouble sleeping at night. Is this something I should be worried about? You could have Insomnia, it is a sleeping disorder. Is there something that I can do about it? What kinds of treatment are available? Hmm I have no idea. Alternative medicine is an option but it is disproven, unproven, or impossible to prove! What is your sleeping pattern like? Do you have trouble sleeping too? Well I'm a bot, and bots never sleep!  I do have information about sleep though.  Jet lag, for example, is physiological.  It happens when circadian rhythms are altered, due to travel going east to west, or west to east. Oh, yes. I hate jet lag. Sometimes it takes me a week to recover from a long flight.
knowledge: Sleep inversion or sleep-wake inversion is a reversal of sleeping tendencies.
