Actually with vaping it becomes pretty easy to quit. You just taper down the nicotine slowly until you're on nothing and eventually you just kind of stop because you don't feel the need to do it anymore.

What about body's response? Is it easy to curb?

I was drinking 2 liters of coffee per day while finishing my Ph.D.. Next week I wasn't drinking, and after that I occasionally drank half a cup per day. This was seven years ago, and I still drink half a cup, because I like the taste of coffee.

I have at least a dozen vaping friends who said they started to stop smoking. Now at least half of them have heavily souped up, customized e-cigs. Two of them are making their own liquids with nicotine, rest are using bog-standard vapes.

None of them stopped smoking or nicotine intake, which was the goal of all of them.

This is such an edge case on quitting a caffeine addiction. 2 liters is an INSANE amount of coffee to be drinking daily.

Kudos to you but let's not pretend this is the average experience of people breaking even much milder levels of caffeine consumption.

I did my research before letting coffee loose on my body.

The coffee acts by blocking tiredness/sleep receptors on the brain, so brain builds more of them to work normally. This is how coffee dependence and tolerance builds.

When you stop coffee, brain detects that the number of receptors is too high and starts to break them down. This is why you get the headaches.

That "one week" period is not an edge case, it's the science of it. If it was proved to be harder on that research, I'd never let my body to reach 2L/day levels.

>I did my research before letting coffee loose on my body.

Was this research similar to you drawing conclusions about nicotine based on the handful of your friends that vape?

Yes. I read papers about both subjects. Also read papers about other drugs because of an addicted friend who I don't talk with anymore.

What I gave was an example, and looks like you're upset about it.

Please keep in mind that while itsoktocry, itsnotoktosnark at HN [0].

fwiw I thought this comment was the snarky one, not GP. Given that this snarky comment also tried to call out GP for snark and refer to the HN guidelines against snark, it also became highly ironic. I would guess that's why you've been downvoted.

That comment is not my best by any means, and I see where you’re coming from, and respect your view. Thanks for bringing it up.

However, language is both subjective and culture dependent (plus, words doesn’t carry tone and sound). If somebody asks the same question the same way in my native language to my face, it’s not only snarky, but it’s rude (and mildly offensive depending on the context).

I don’t think I’m expected to know the all possible cultural styles, and take anything and everything kindly and politely, all day, every day.

Henceforth, I tone matched the comment according to my perception. I might be correct or wrong according some dominant discussion culture here, and people may perceive me the snarkier one according to their cultures. I can’t judge them, but this doesn’t change the fact that the style of question is rude on my side, and I have the right to respond equally (to my perception).

Normally I’m a much softer person and don’t write sharp comments, so that one is an exception.

Lastly I’ll be posting a research tome on caffeine addiction/withdrawal to the person who asked, so you might one to follow that thread too.

Have a nice day :)

All make sense to me! And yes for sure there was some snark in the comment you replied to. If it helps, the specific part of your comment that I felt elevated it to a higher level was the reference to their username, which was ad homimen/personal snark, whereas both theirs and the first part of your reply was snark directed at the research or the methods.

Likewise have a nice day, and thanks for the tip on the research tome! I'm definitely interested to see it :-)

Honestly cigs were way easier to quit cause theyre inconvenient. Vapes can be used anywhere discretely.

Easier != Easy

Can you link a study for this? I'd like to read more.

Here's a small research tome I collected yesterday. Please note that I have access to all of the papers' full texts. I was unable to find the original papers I read at that time (i.e. 7 years ago!), but found the video which brought me to the entrance of the rabbit hole.

- The base video I have talked about is from TedED. It's here [0].

- This study was done on rats in 1985 but verifies that caffeine tolerance is real [1].

- Another controlled study on humans about caffeine tolerance [2] involved one group taking caffeine and the others taking a placebo. Caffeine drinkers taking the placebo reported withdrawal symptoms, and non-drinkers taking caffeine reported overstimulation.

- A meta-study [3] details the symptoms and durations of caffeine withdrawal's effects. The paper cites that effects persist between 2 to 9 days, and the peak of the syndrome is around 20 to 51 hours. It also notes that caffeine introduction during this phase alleviates symptoms (This study basically confirms that what I have gone through after I stopped drinking coffee as I noted in a previous comment).

- This interesting study [4] explores the body's caffeine response via blood pressure change. Subjects are administered high doses of caffeine, and blood pressure is monitored. After day three, the blood pressure normalizes, and spikes disappear. The abstinence required to reset the pressure response is less than three weeks, pointing that the body resets caffeine tolerance in less than three weeks.

If you need the papers, or want more resources, please let me know.

Have a nice day.
