Is that a reality-based statement, based on some sort of data? If so, please share. Since I can remember, I've had episodes of pretty gnarly insomnia, and have sought all manner of medical and other help, from mainstream to fairly ridiculous ones done out of desperation. I tried cardio, weight-lifting, slow-walking 5 miles a day; I quit drinking, quit smoking, tried drinking more, stopped caffeine, tried meditating, sex every day, minimal sex, vegan diet, paleo meat diet, calorie-restricted diet, melatonin in various dosages, all-lights-off-at-dusk, blue/fullspectrum light therapy, read only books for entertainment, play 4 hours of video games every day, ice baths in the morning, and lots of other last-ditch n-1 experiments. Ambien is the only thing that helped. I'm pretty leery of it, what with all the stories about people having sex with strangers in the park and not remembering. Also, I really really don't want to develop any new dependencies that make it even harder to sleep naturally. However, if I have 2-3 consecutive nights where I can't sleep more than 2-3 hours, I take an Ambien and then I sleep through the night. And the next day I feel like I slept through the night. That happens maybe on average once a month (but the cadence is more like 2-3 months no problem, then several bouts of insomnia in a month). So while I still have the insomnia problem like I always have (43% through my projected 100-year life span), the Ambien makes it manageable.
