> My ex wife told me I'd once answered her phone call in the morning and had a complete conversation only speaking absolute nonsense until she hung up. I had no recollection of that at all.
I've had that several times. The kicker is, I actually did make enough sense that she didn't suspect I wasn't awake, and it wasn't until later that I learned from her that the conversation happened - usually because I agreed to something, or was given important information, which I had no recollection of. The phone log, of course, confirmed a conversation took place.
Melatonin sounds like it may work long-term, but at this point my wakeup time is set by our kids, and my bedtime is set by my acute revenge bedtime procrastination, so sleep deprivation it is :/. I wish there was something that could immediately force/reset the circadian rhythm, which I could use on business travel.

Two things that might work in these cases are melatonin and bright "sun"light in the morning. These should control the natural circadian cycle. I haven't found success, yet, but haven't tried too hard since I can live with my schedule.
