Well, that's a great attitude, Françoise! But, do you think it might be better to taper more slowly? Maybe go down by 20 % of your usual caffeine intake, and stay there for 2-4 weeks? You don't want to get caffeine w/d, and you don't want to exacerbate dysautonomia.
Also, what about decaf (good quality, safe method) coffee substituted for one of your regular coffees?
Also, what about coffee ice cream? We need to fatten you up! ;)
