My body and brain are mostly caffeine at this point, so I know a thing or two. I’ve also done more than a few rounds of cutting caffeine out for a few weeks or more.
In most people you don’t have to have a protocol for caffeine withdrawal or eliminating it completely. It sucks really bad for about 48 hours with a headache that is just shy of a migraine but once you get past that, all that is left is being a little more tired and run down until your body starts to adjust.
I’m not sure if you meant that for me or the dorkus I responded to but I already knew most if not all of that.
