Answer: Milk is milk despite the fat content, it all contains trytopahans.I have some other advice on how to treat insomina.When you go to sleep make sure you do it in a dark room, a room that should only be used for sleeping, pull the TV out. Make sure it is a relaxing place to sleep as well. Hold off on any caffeine at least 6 hours before bed, and the exercise as well. One-half hour before you go to bed dim the lights a little, this will increase the body’s natural production of a sleep hormone called Melatoin. A glass of warm milk will do the same. When you go to bed compose yourself for sleep, relax and push out all thoughts of the day. If you cannot do this then think of something else, something that you like, even a sexual fantasy. If you don’t fall asleep in 20 minutes then get out of bed. Then do something quiet, like watch the TV on low volume or read, but don’t do this in the bedroom. After 20 minutes try to go back to sleep again. If it still doesn’t work then get up and do something quiet, and try it again in 20 minutes.
