@ekopoc I would normally add like one, in one cup. But! In special occasions like staying up late I will add about 3-5 packets of black coffee in one large mug to drink.. I would also use Luke warm – boiling water for best effects, this would usually get me to stay up to 5 hours, per cup, but, at this point of time I can only go for 2 unlike my usual 5 hours. And after 2 hours I will collapse and sleep. I have a pretty unhealthy sleep schedule ok!
