Thanks for that tidbit! And yes, so I make sure to sorta mix it up, space it out to not be dependant on the caffeine/with withdrawals.Ironically, presence of a caffeine headache is largely due to withdrawal symptoms after not having caffeine, when one is used to consuming it. Traditionally, due to caffeine headaches after the 25 hour fast of Yom kippur, many Jews have coffee as their first drink after sunset after.
