Step 2: refuse to use it outside your home. That's more active, and may require a commitment. You can start by allowing yourself to drink one every other day, to mitigate withdrawal symptoms.
Decaf etc - I can't say how useful it is, I wanted to cut coffee and not replace an habit by another one. No more coke or redbull either, since the problem here is caffeine: the active ingredient in coffee is also present in coke and redbull and the likes (pepsi, monster, ...)

So far, I have been very dysfunctional during the first 2 days, and at my 4th day I feel normal. I was expecting to feel bad for up to 9 days.
It has had an interesting effect: it seems like I need less sleep, something I noticed when I tried to reduce the dosage these last weeks (not quitting altogether), and completely counterintuitive!
It may be just a normal variation due to a very small sample size. I would be curious to see how much sleep I will need in a year from now. Of course, your results may vary.
