Discussion: XL1 Energy Drink - help!

Back in 2001 (or maybe it was 2000), XL-1 sponsored the Birkie and was, by far, the best sports drink I've ever tried. Ever since, I've been looking on and off to purchase some, and have only found references and reviews of the stuff (all positive), and every now and then a post that it "can only be bought in Norway." It must be sold somewhere that is accessible to us US-bound creatures, do you have any idea where?

Thanks!
