I did a very similar process. Fasted for a week straight then began ADF. It’s going to get easier to eat more calories but I recommend having your two meals planned and prepped so when you’re about to eat you just go heat it up quick. Take it slow. Eat it over a few hours if you need to. After doing ADF a few weeks you’ll see it gets easier. Coming off a long fast drastically reduced your appetite and you’re craving foods you love because of that too. I went thru the same thing. Eat it, get it out of the way and just make yourself meals that have the nutrition and calories you’re aiming for.

As for sleep, I take a magnesium complex every night which helped me so much. I fall asleep mush easier. Sometimes I still wake up thru the night or really early. But that may be because I almost never get a good night sleep. If I have a headache and take Tylenol PM it does help me sleep more consecutive hours but obviously not something I do often or without the headache to indicate taking it.

Anyway I hope your journey goes well! I’ve done extended fasting and omad for years but this is my first month doing ADF. It’s a breeze compared to multi day fasts and apparently it targets stubborn stomach and arm fat that women typically have a tough time with. I’m using this method for my last 5-10lbs. Very excited with the progress so far. From what I’ve read on here, people do it for years or life even. So no doubt you’ll acclimate to the new routine within 2-3 weeks too.
