You're boiling it in a pot, right ? What are the best combination you got so far ?
Also, couldn't you just drink tea (black tea ?) with lots of sugar for the same effect ? Did you tried ice boiled soda-tea ?
Boiling it in a pot, yeah, generally. You can also microwave th'soda and steep in that, comes out about the same -- just stick a toothpick in the bowl or cup with the soda to make sure you keep the surface broken, helps make sure it doesn't explode. It doesn't take very long, either, two-three minutes at the most, iirc, just nuke it 'till it's hot and flat. Best combinations so far have mostly been mountain dew with cheap-arse honey/lemon/ginseng wal-mart obtained tea -- the purple stuff they had years ago was the best, but the normal stuff works fine, too. Comes out kinda' grape-ish, just... sweeter. Secondary tier's been boiled Barqs root beer with th'same green tea or gojiberry tea, which... I can't really describe in words, beyond "sweet". Some orange minutemaid with th'same honey-etc. green and some extra honey turned out alright too, when I was feeling a lil'sick. I wouldn't recommend orange soda with orange-infused tea, though. That didn't go very well (children's aspirin, yo'.). I think I've tried black soda-tea once, but I can't recall with what. Mostly I just throw together whatever's on hand and see if it works. Usually it's decent enough I can drink it, if not very memorable either way.
I've tried cooled, yeah, and it's still pretty decent. Did that with coca-cola and green, and I think Barqs and... something. Drank the remains of the same pot over a few days a couple times. As for th'lots-of-sugar thing... I actually haven't really tried that (I usually use honey if I want to further sweeten my tea), but I imagine the texture'd come out different, and likely the taste. It's not
just raw sugariness, but that's the closest description I can come to it.
I just stick to diet soft drinks. All of the soft drink flavor, none of the sugar! And caffeine I guess... not that it does anything to me.
Diet soda's arguably worse for you than regular soft drinks, from what I understand
I can't stand the taste of most artificial sweeteners (especially in drinks), though, so diet's mostly out for me.
