Ok, many studies have been done on melatonin (the brain chemical that is responsible for moods, growth, and controls anxiety and phobias) and how it is affected by the amount of light onyou sleep with at night. Here is a site on it:

I have slept with some light on for years, and right when I started sleeping with more light, my anxiety and emet would get worse. I'm also constantly tired, dizzy, and generally feeling weird (and an imbalance in that chemical also causes n*!). My body developed an unnatural sleep cycle and I think my anxiety got worse because of it. Well, this week I started sleeping in complete darkness. I am feeling better already! I am sleeping through the night and not panicking in the evenings about v*ing at night, like I usually did. So, maybe if some of us emets who sleep with light on, start sleeping in darkness, emet will get a little better! Just a weird theory...now take the poll!
