Hi, I believe it does. The proceding post is correct about the book Potatoes & Prozac. A little history about me. I have a sleep disorder resultant from a very serious previous concussion. Now days called traumatic brain injury (TBI). Most patients with TBI history will develop migraines & sleep disorders. They are related. TBI pts. do not produce enough seratonin (needed for sleep, too) in their brains, as a result of the damage sustained. A lack of seratonin has been linked to depression, of course, but also to migraines, & sleep disorders. I combat the lack of seratonin through exercise, rather than the traditional route of antidepressants. I hurt myself a while back and gained a little weight from not being able to move around & burn calories. I have been losing the weight well, and decided to cut down on my carbs (what was I thinking!?) for a while. I did lose weight, but after about a week and a half of that, I suddenly started only sleeping 3-4 hours a night, would wake up for about 2 hours in the middle of the night unable to return to sleep, and then sleep another 2 hours (sometimes on that latter sleep). I was averaging 3-5 hours sleep a night & I need 9! I almost got killed in a wreck yesterday from my brain not working right from the lack of sleep. I told family & friends I have got to get some sleep & googled up “Does popcorn make you sleep?” and found this board. I then realized that I had been eating healthy popcorn almost daily, because we own a popcorn machine for business (pop with sea salt, a few tablespoons of olive oil, and the popcorn). Well, I slept 4 hours, I did wake up, took a melatonin & triptophan supplement, and went right back to sleep instead of waking up for 2-4 hours. It was pretty continual sleep. I got a total of 7, which I can function on, but I really do need 9. I ate the popcorn at night about 1.5 hours before bed. I usually consume it between 3-4PM, so I am guessing my body has had time to digest it, and the triptophan has been sent to my brain by then. BUT, that is the best sleep I have had in a week and a half. I ate only 1 bag (like the kind they have at the circus). I usually eat 2 bags, but cut back b/c of not wanting the calories so close to bed. I’m going to eat 2 bags back to my old time from 3-4 PM and see what happens. I am wondering if it needs to be a cumulative effect or what. Will post more as I see on this experiment. Great idea for dissertation! Oh, almost forgot, was taking the triptophan & melatonin supplements when also having the insomia. Would take when woke up in middle of night. Between the 2, I should have been falling back to sleep, not lying awake for 2-4 hours.
