Does Zbiotic hangover cure act as a stimulant?

I’ve used Zbiotics about ten times to prevent a hangover, and it works great but it’s starting to give me a side effect that’s a tad concerning. The deal with it is it’s a genetically engineered probiotic that claims to quickly break down the enzyme produced by alcohol that gives you a hangover. The good news is that when I use it I really do feel much better than I would otherwise. But I also have a ton of energy the next day, like more than I normally would. I’ve also noticed that it can also give me a touch of insomnia and make me feel like I’m highly caffeinated and not in a good way. Given this product isn’t FDA approved, I’m now wondering what else might be lurking in this elixir. Has anyone else had an experience with Zbiotics acting more like a stimulant or caffeine drink? Is it possible that a probiotic would do the same thing — give a huge jolt of energy?
