What is the best method to use to get back to sleep after awakening in the middle of the night? (ie: 2:30 am) and needing to use the restroom. Deep breathing, visualization using acupressure points are some methods I have read about. I also have a Sun Alcon chi machine. Using it around 9 pm causes me to wake because of using the restroom. Drinking 1 to 2 cups of water is recommended after using the machine in order to flush out toxins. Any suggestions on how to stop waking up at 2:30 or 3:30 am?
