30 days of not drinking fully caffeinated drinks - couple of decaf coffees here and there, but otherwise no non-trace amounts.
So far not worth it, and rather unsure if I'll be continuing this experiment. I have zero motivation and get absolutely nothing done, work or personal. If /r/decaf is to be believed, things tend to turn around for folks around the 4-6 month mark where productivity returns.
What I don't know is if I can wait that long.
Brighter side: anxiety is near-gone. Life is calm.
