I vaped for a while and my take was that you felt worse in general with the ability to feel better on command for a little bit.

It may be the remnants of addiction speaking, but there was something about vaping that elevated certain scenarios. I loved standing at a tall place and watching the cloud dissipate into the scenery as my eye balls and body relaxed from the nicotine. Whether it was a cityscape or a high hill, it was just lovely and I remember it fondly.

The very last time I vaped, I was in the smoking lounge at the Singapore Changi airport. It was a rough room with harsh dystopian concrete benches. In the ill lit space, I sat down and took my last drags. As I inhaled, a middle aged Chinese business man in a suit sat down next to me and silently enjoyed his cigarettes. Then we went our own ways without saying anything. I thought it was a good last time.

Also, I'm sorry, but at least for me and a friend we found it hilariously easy to quit vaping. We simply just "stopped" and that was that. I found it much more painful to quit caffeine (which induced in me a fortnight of withdrawal symptoms, sore bones and fevers).

To quit caffeine, taper down intake slowly over a few weeks.

Caffeine pills (nodoz) are probably the best way to reduce intake slowly that I've done so far - easy to measure based on broken tablets.

There should be a product we could buy to do it because the progression would be satisfying in itself. Unfortunately one-off product categories never sell enough to make such a product profitable.

I've also done it slowly over a few weeks using instant coffee. It's a bit unpleasant at the end if watered-down because it's so weak. I also just reduced intake having the dry granules on a spoon (unpleasant but doable!)

Every few years I get bored of coffee shops or I get slight allergies to espresso coffee so I give up again.

Cold turkey gives me nasty headaches for far too long so I don't just stop any more.
