So here's the thing. When I went off caffeine it took at least a month before I realized I wasn't having any withdraw symptoms. Headaches and whatnot. Then I had a half a can of Pepsi and was bouncing off the walls. So, if you need to stay awake for any reason in the next month and/or won't be able to handle the withdraw, stay on caffeine. I did it during the summer when it wasn't as difficult. Red Bull is evil, just saying.

You wanna detox? Easy, drink more water. That's all you need to do.
