Great read! I agree completely with this: "I choose to refrain from drinking coffee unless I feel I really need it".
I refused to become someone who needed coffee to just feel "normal" or have energy for work so I decided to get off it completely 2 months ago. I do miss it, especially the creativity boost, and quitting was a bitch at first. Now my energy levels are way higher than they used to, I sleep better and if I decide to treat myself once in a while it will taste even better with a stronger effect. Win-win.
