Caffeine must be one of, if not the, most used drug. It is vital to the operation of more or less every industry.
I mean I’d like to follow that advice, but my coffee consumption is quite low actually. I usually drink half a cup of coffee a day. Some days 2 half. And this only in the morning.
The problem is that if I don’t, I tend to get quite the bad migraine around noon. So I prefer to simply have it. Also it does boost my mood and productivity in the morning a lot. I don’t really feel like I need to stop it, but I appreciate your advice, I do know some people who drink an awful lot of coffee which even I find kinda disturbing.
