Caffeine is delivered quite differently based on the brewing method. I find that 4 or more shots of espresso a day will lead to an eye twitch, while one or two cups of Philz deliver the caffeine far more smoothly.

French press seems to be somewhere in between, the extraction is different than pour over. Philz's extraction time is even shorter than a regular pour over. They use a lot more beans than Blue Bottle but the water flows through the grounds much quicker.

If you can't go cold turkey, try avoiding espresso and French press and the jittery feeling might subside.

This has very little to do with extraction and everything to do with temperature and time (pyrolysis) and the subsequent formation of various monoamine oxidase enzyme inhibiting heterocyclic aromatic amines from protein amino acids.
