I worked the night shift for 18 years and thrived. I slept well and pretty much kept to my night schedule on my nights off. The problem began when the state closed the hospital and I no longer worked nights. I retired. It's been three months and I can't sleep at night. I'm a wreck. I've forced myself to stay up during the day with an occasional nap; but generally I'm exhausted. Has anyone else had this problem? I hate to start popping pills.
