I remember two years back. As my Lenten sacrifice, I tried not to ingest any kind of caffeine in my system during Fridays. Oh what a nightmare. I turned into a monster, an ugly, cranky, generally foul and vile version of me. I cannot see myself going through that again. Just thinking about it makes me shiver and feel cold, like a dementor was about to suck all the happiness from me. I don't smoke, I rarely drink. But caffeine is my poison.
