Have you tried a "coffee nap"? I find that if I just drink caffeine to counteract building tiredness, it's not going to help. Like sponging up water from a broken faucet. But if I lay down and rest (this doesn't have to include sleep, I set an alarm and let my body do what it needs, but the primary factor is giving your brain the peace it needs to process and flush stress accumulated through the day, in pseudoscientific terms), and then drink coffee, I'm reset and it can take effect.
The "Coffee Nap" is where your drink a cup of coffee (quickly, I guess), then lay down for 10-20 minutes to rest, and by the time you get up the caffeine will begin to kick in. I find that process to be a bit more stress-inducing.
