Try drinking tea instead? With tea you don't experience the same crash as you do with coffee. It's a much milder, less jittery lift. The compounds in coffee stimulate SNS (fight or flight) response and stress levels, which is great before a hard workout, not so great if you want sustained energy. I try to limit coffee to pre-workout only, especially if you want to put in an extra hard effort. After a few days drinking it, I start "needing" it to feel normal and I end up worn out and tired.
