I did it last December.
The fasting began at midnight of a Thursday so the primary "lunch" that I skipped was the Friday breakfast and I went ahead until Saturday at Midnight.
The initial 24h you will feel a slight (but persevering) feeling of appetite however physically and rationally you will be fine (very nearly 90%, I would state).
I prescribe you to drink bottomless water (+ a coffee when you feel somewhat drowsy).
The second day (the Saturday) the feeling of appetite sponsors a little however you will feel increasely drained and it will take you somewhat longer to do basic undertakings and furthermore concentrating on specific things.
Startlingly I needed to work hard that second fasting day in light of a crisis at work (I needed to walk a considerable measure conveying some overwhelming stuff to a few spots and furthermore center to keep in touch with some long business related messages) and, as a result, I got an exceptionally solid cerebral pain + solid feeling of regurgitating which I can just connect to the way that I was fasting (and not drinking enough of water).
I interfered with the fasting after 48h.o
