It's day 1! Ouch, ouch, ouch
Good luck. Taper if you need to. I did cold turkey last time and had my worst migraine in years.
ugh yeah if you get migraines do not fuck with cold turkey. I don't and it's less bad but its still a lot easier if you taper at least a little.
I had to switch to tea-based caffeine this year due to nausea/anxiety issues brought on by caffeine, and the crashes were way too hard. it's been more manageable than I thought, I wish you luck
Is there any science on how long one needs to do this to reset caffeine tolerance?
Hard science idk, but article I read quoted a "coffee researcher" as saying it should be about a week. Probably varies depending on a bunch of factors.
I don't think it ever totally resets. mine goes right back to the way it was when I was consuming large amounts of caffeine even though I only take it once every couple of months now. but it's never taken me more than a week to break the caffeine dependency.
Me, literally at the coffee shop rn
Actually though I might need to do the same. I can survive a day or two break but I'm notably dull and lately I've been feeling a little jittery, mentally at least, but still tired :(
Good luck! I found that herbal teas helped replace the ritual of drinking caffeine, which made the caffeine break a bit more tolerable.
