Generally the only time I see dawn is when I haven't yet gone to bed.

And I have no need to get up early, nor to bring any food items into the bedroom -- most days, my time is my own; I do with it as I will. The major point I was making is that the technique for really satisfying vaping is a bit different from cigarette smoking, though a) when you first start vaping, you may not be fully aware of that difference and how it can affect one's satisfaction with vaping, and b) when one first gets up, one is not often thinking consciously about anything, just following rote patterns while one's brain wakes up -- that last, I think, is what was getting in my way, because the rest of the day, I didn't have any trouble with vaping satisfying my urge to smoke -- only during that half-awake time when the brain is operating somewhat in 'auto-pilot' mode. Once I actually realized what was going on, I could correct the problem -- and the result of that correction was immediate: smoke-free starting from that day.
I did go thru a phase where I took a special "morning vape" -- high nicotine, low TH -- to bed with me, and started on that the moment my feet hit the floor in the mornings, but after a few months, it was no longer necessary; now I generally wait about 15 mins before I have my first vape, to give my asthmatic lungs a chance to do any coughing up and then settling down; when I smoked I had to wait about a half hour on that, so 15 mins is no hardship. But yeah, at first I had to power thru the morning asthma, to avoid morning cigarette cravings that might derail the whole effort.
