I'm on day 2 of no caffeine inspired by @jrg.  I'm very skeptical.

One thing that's helped me is massively limiting my intake. I probably have half a cup a day now down from 2 cups

/ethereum foundation | opinions are my own but more than likely they come from Vitalik's blog paragraph.xyz/@chaskin

I'm the opposite, I don't love the taste of coffee, just want the effects and even a small amount helps me

Do you drink decaf?  Or just a half cup of regular coffee and that's it?  I've been drinking decaf because I still love my morning coffee.  It does the job, but isn't as good as regular coffee.
