Stop: Stop eating anything for at least 2 hours before going to sleep.See your Physician for a complete physical, including lab tests. Sounds like some life-style changes will be required.

Sleep Hygiene is Key: Keep reg. bed & wake time. Make routine: warm bath /shower, aromatherapy, read, or light music. Sleep in dark, quiet, cool room w comfy mattress/pillows & no work materials or computer. Bedroom only for sleep & sex. No food 2-3 hrs, caffeine w/i 6 hrs, alcohol or smoking w/i 2 hrs of bed. Exercise at least few hrs before bed. No naps. Retire only if tired. Deal wi problems at another time.
