It gets better. Give it 6 months and you’ll be flying through the days. Try and make it easy on yourself. The day before your FD make sure you go very low on carbs, especially processed carbs. I used to dream of eating all the time on fast days, how I would eat like a king the next day. Come the next day I didn’t really eat that much. Now I don’t even think about food on FD.

It gets better. When I started I was constantly looking at what had how many calories and how much I could have. Now I can do a two day water-only fast. It helps initially to have something else to do at the standard meal times. Sitting watching others eat whilst you do not takes a bit of practice, but that too is achievable. After a while people accept that some days you sit and chat and drink water whilst they eat.
