I don't really feel woken up by coffee, could that be related? Nothing helps more than being hydrated (after 8 hours of no water) and ample sleep time.

There's also a question of tolerance of course. If you drink coffee every day, then after a while you build tolerance and the effect becomes much milder. In order to assess whether coffee is effective you would need to take a break for a week. I know that when I have no tolerance, a strong cup of coffee has a very strong effect, I feel an instant mood lift and become much more active, I want to spend energy.
