I didn’t know about those pills but they do contain caffeine as you say, so it was no good for me even if temporal. Some people switch to decaf coffee only to find out that it has some caffeine and still affects them. I can’t vouch for that personally but seems a common occurrence.

But it’s a good alternative for those who see it as an impossible task, and also yourself. In my case I had to take NSAIDs - which I very rarely take - for a couple days just to get by (since the vasoconstriction “feature” of coffee wasn’t present anymore, headache ensues) but then I was ok, just tired for some weeks.

Congrats on quitting!
