My 87 year old mother would tell you, I WAS BORN WITH IT!! Poor mom, she never had a break with me. I NEVER, EVER took a nap (but then I didn't crawl either and didn't walk until 12 months) so I was up screaming for toys! I know I COUNTED on my kids taking naps during the day just to get things done. I don't know how she managed (I was a tough kid) but she did.
So, yes, I even tried Ambien for a while, just to get a solid 6 hours of sleep. Since it has a "half-life" of 6 hours, it never got me past that 6, and I finally figured out, my body would get the sleep it required without me trying to get it to sleep more, so I quit the Ambien.
So, yes, you have a friend here with multiple decades-long insomnia!
