I’m currently 36hrs in my first EF and feeling great! 24 was the longest I’ve done, but I wanted to push through dinner last night and hubby was sweet enough to fetch his own eats so I didn’t have to be exposed. That really helped. My waking BG was 4.6mml and my Ketones was 1.9mml. I have an aqua class this morning, then I’ll break fast at lunch with my buddies, so that would put me at 41hrs for my first shot out of the gate. Not bad for me. I think that building up with IF and occasional OMAD certainly helped me too. I can see more and longer EF in my future. It really does get easier and I seem to get a hellova lot more done when I’m not in the kitchen cooking stuff!
