I've been off and on with coffee for about 30 years, with a tendency to ramp until I'm drinking way too much of it and then have to take a t-break and suffer withdrawals. it's an effective focus enhancer but only if I ramp the dosage. longest time off was about 2 years that coincided with a break from intense problem solving - my natural resistance to intense focus feels fully restored after a couple of months and it's great for my temperament (more aloof, pleasant, not everythings a problem needing to be solved) but as soon as I feel like I need to focus it's coffee time and we're back on.
