Reply To: How come I got a headache after the fast instead of during it?

So I have fasted on multiple occasions. I usually have 32 oz Gatorade a day two days before and day of fast. Then day after fast and right after fast same thing. I taper off of caffeinated beverages a week before. If I haven’t drank a ton of soda coffee etc, then I just stop. If not I reduce amount in half per day then go to e/o day. So if week before I wound up having two can of coke a day, I try to do 1 a day for two days, coffee based frappe two days later with no caffeine in between and nothing after. I broke this fast with bagel and schemear and ice cream plus gatorade.
