I went from seven cups+ a day to zero caffeine - I was most surprised that I didn't suffer any sort of physical withdrawal - I was anticipating immense suffering.

I used a product called Wean Caffeine to successfully avoid the headaches. It steps you down by 10mg every three days. For anyone wanting to quit, I highly recommend.

Can confirm. Went from drinking 2-3 cups a day to no coffee about a week ago and the headaches were very bad for a solid two days. As in, lay on the bed feeling like an unproductive potato bad.

That was the worst of it though. By day 4 everything felt back to normal. Hoping to keep this up for at least a month or two.

Having been addicted to caffeine and nicotine I found the migranes were equivalent, only with nicotine it would be every 30 minutes after injesting rather than 5 hours.

In both cases they were gone after about a week or two, but I could see how it would be difficult for people who have an easy time smoking (low vs high sin taxes, happen to be at places where you can smoke all the time like your own car and home vs. a restrictive apartment and public transit, whether or not your friends also smoke all the time). My addiction was only for about 2-3 years, too, not half a lifetime like with some people.

Yeah, I've gone through them. Often times it starts on a Saturday afternoon since I don't drink coffee as frequently on weekends.
