How do I get my caffeine? Any way I can being pretty poor. I'm quite happy with most any tea, coffee, or soda, but I have to be extremely careful with energy drinks, as I'm allergic to guarana. It won't put me in the hospital with an allergic reaction, or anything like that, but it is like hitting the empty button on my large intestine, which is unpleasant. So I tend to be limited in choice to the non-carbonated Rockstar sugar free energy drinks and Rockstar Zero(also sugar free). The good news is that they're at least sweetened with Splenda/sucralose.
For soda, I lean towards Wild Cherry Pepsi, Pepsi, and Mountain Dew. I love soda generally so caffeine-free sodas are also lovely to have. Coca-Cola though, along with some other colas... They're not sharp enough and they kinda taste like what I'd expect what a glass containing sweat wrung from a well used and never washed gym sock to taste like. I don't begrudge people who like Coke and similar colas, I can stand them if they're what's available, but Pepsi-cola is the superior cola.
For coffee, generally I only have no-name repackaged taster's choice instant to hand, which I can stand, but it's not very good coffee. I sometimes go to Peets' or Starbucks... Still I desperately miss one thing about my old town. Dutch Bros. Coffee... That stuff makes any other chain coffee seem pitiful.
Also I always sit on a large stash of teas, I especially love Stash Moroccan Mint Green tea.
