Whoa, I must have totally missed the second page of this thread.
Kobracom - The carbonator bottle you posted the link to is the one I've been debating. It comes with cola flavours that would likely do the trick, but so far I haven't found any of these in Canada. Their syrupy packets are also very expensive, so my current plan is to go with that bottle, the Sodastream syrup stuff (that I think one can buy at some home stores in Canada, Bed Bath & beyond or something like that), and get some of Pat's Backcountry Beverages activator that creates the fizz. The only thing i haven't found out yet is whether those fizz activators can only be used with their syrups, i.e., if there's some ingredient in there that makes those two work together, or if their activator will also work with the other stuff.
Didn't get around to MEC today to get the nuun tables, but those are another options.
prother - I'll look into the alibaba stuff more as the powered would seem like the easiest solution. A lot of the stuff seems to be coming from overseas, so I'm more curious about the ingredients. Then again, as you suggested, reading about how bad Coke is for someone, … ah, to heck with it. I can ditch the habit after North Coast Trail :-). But yes, I am aware of the crap that comes with this stuff, especially the aspartame, and am trying to cut back. When doing a hike like that though, a cold fizzy caffeinated drink sure gets me going though.
As for the McD's syrup, I'd really love to try it, but am actually doubtful that any manager would be willing to sell some. Of course no harm in asking, but I seriously doubt that that would work.
Just came across this … a strange video out of some guys's kitchen, but the gadget is small and portable. I need small and portable! http://www.fizzgiz.com
Seems a little sketchy still, so I googled it some more and it's actually a Canadian product: http://eco-source.com/items/househol...fg1-detail.htm
Anyone know where one can buy those CO2 cartridges (the food-safe kind)? Is that something that a place like Canadian tire might carry? What do people normally use these for? Looking at this, it looks more and more promising - use it with any regular bottle, dump in some SodaStream syrup and water (filtered from a water source; I am not carrying water), and fizz with a cartridge. I might be in business :-D.
So, apart from those two options I'll also try to find some Fizzy somewhere (anyone happen to know of a place in Calgary that has the stuff by any chance), mix it with nuun and water, and then I'll have a 'test week' at home. If this substitute will get me through a work week, then it should also do on trail.
