I haven't been able to sleep since I was a baby so it isn't my routine but I am lucky to get 5 hours sleep a night. What could be stopping me sleep?

Insomnia Problems. Many factors can contribute to insomnia; here are a few: low progesterone, low blood sugar causing release of adrenaline, low levels of melatonin, excessive neuroexititoxic items (like aspartame, nitrates, nitrites, msg, fried foods) in your diet. Stimulants (like coffee) too much light exposure late in the day. Not enough natural light exposure early in the day. Lack of darkness at night.
