Can only speak for myself. I got better results when I went to sleep immediately after drinking the olive/lemon stuff compared to when I could not sleep and sat on the computer like you until morning. I have read view to the contrary. One receipe (grandma Nada I think) says walk all night and another says go to sleep immmediately on your right side. But neither says sit up all night. (ofcourse there may be still more views)
Maybe you could go to bed with a boook....? Just a thought
