I'm in the same boat here, was diagnosed with ADHD at the age of 28 and realized pretty fast after that I had been self-medicating with massive amounts of coffee. Was up to 8-10 shots espresso a day when I was diagnosed. I was jittery and having problems sleeping, but could only focus as long as I continually ramped up on the caffeine. Adderall has made a big difference for me- I've gradually cut the caffeine to a 2 tiny coffees a day and my focus is way better than when I was drinking latte after latte. No issues with ramping up either, it's been a couple years and I'm still on basically the same dosage of adderall.
