I only sleep 2 to 3 hours a night. yes I am overweight, but the weight came after the lack of sleep. Before this began I would go to the gym 5 days a week. I have vestibular damage in the right ear, I have had nonsustained atrial tachycardia, and restless leg syndrome. Social Security says I can work but my doctor says not to drive. I can fall asleep standing up but, I don't stay asleep. Please help.
