I hear you with the ritual of dinner to switch gears. I would save a specific fasting-friendly drink to sit down with at the same time. Bonus points if it takes a few minutes to create and then some time to savor. Something like a new loose leaf decaf tea that you can brew and linger over, or maybe soda stream some water and macerate in some mint or a add a little lemon juice. If you only let yourself have it at the end of the work day it will feel like a treat and create a similar cue as dinner.
Ya this is one of the biggest problems. Boredom during eating time. Or just feeling out of place mentally.
The other big issue for me is after 3-4 days I start feeling mentally kinda out of it. Even if I take electrolytes or whatever. Coffee can help but I don’t like to drink too much of that.
Change up your nightly wind down routine. Maybe try a shower and then some hot lemon water or herbal tea? It’s warm and filling. You could also find a show to watch a little of or a book to read with your tea and use that as your end of day marker. Hope this helps 🫶🏼 Happy fasting! 🥳
