For those 65 to 85 years old who get very little sleep (not enough), is there a medication without side effects that can improve sleep?

For a long time I have slept very little. I thought it would improve with retirement but 4 years later, no improvement. I don't have a very stressful lifestyle, I eat well and my alcohol consumption (only red wine) is probably higher than average (2 bottles per week). My doctor is not too keen on prescribing me a sleeping pill...
