I know that if you don't have ADHD and you take ADHD medication [more specifically Alza], you will get insomnia, be more alert, very chatty, amongst other symptoms, and if you have an energy drink [in this case Relentless] you will get a buzz for an hour or so then get a low.

The thing I mainly want to focus on is the staying awake part, but other details are cool, too.

It's just, seeing as Alza will keep you up all night, and Relentless will give you a high for a very short time, won't they just cancel each other out?

Or will they give you a completely new set of symptoms?
