Never tried it in my life. Pretty sure you can get it here in the UK, but most of those style drinks (monster etc) look so artificial that my own innate cowardice keeps me away.

That said, I barely drink soda since the sugar tax, as all the soft drinks now have sweeteners that I taste as bitter - even my national drink (Irn-Bru) has been ruined.

So, with that in mind I'd probably be keen to try US Gatorade, as I'm guessing it's loaded with sugary goodness
