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.
I usually only have trouble sleeping from jet lag.
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 don't know. 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?
Jet lag is a physiological condition which results from alterations to the body's circadian rhythms resulting from rapid long-distance trans-meridian (east–west or west–east) travel.
