I as the "coffeedrinker" stopped drinking coffee and energy drinks. I do not want to be anyone's boss but if you think you can live without them, do it. I am fairly young and after a long period of frequent consumption ( 1 coffee or drink per day), I was waking up at nights or struggling during the days from constant heart pains. Now 2 months later this phenomenon happens seldom and I feel better and more refreshed after my sleeping. I know this is irrelevant but I know fellow devs that overconsume these kind of drinks. At least if you can limit your dose! :) I just want everyone to be healthy and happy! Have a nice day! ♥
