anything you eat?

I don't know what I am telling you here will be the same case.
I noticed once that when I went to a place to eat, I will have similar problem, wake up around 3 or 4 o'clock in the morning. When I eat at home, the symptom disappears. I don't know it is the food I had there or anything in the food caused that issue. Other people in my house seem fine. Anyhow, I may not go there to eat anymore. You can think about it and it may help. gook luck!
