I limit myself to one mug in the morning and another around lunch if I need the help on the days I do drink coffee. I try not to build up a caffeine tolerance since it's the next best thing to ADHD drugs for me. If you just like coffee, switch to decaf and only drink caffeinated for when you need it.
