Is caffeine worth the anxiety, withdrawal and crash?

I know this is a personal question, but it's a hard one. Caffeine or Coffee really drives me to finish my projects when I'm lazy and lack my own will-power, but the withdrawal I am feeling now is jut horrible. I'm irritable, lazy, tired, drowsy and foggy.

Sure, you can combine it with L-theanine and drink the coffee after a meal, but is it worth it, overall? Thoughts?
