I know of something that might aid your need for caffeine. Try V8 V-Fustion +Energy.
It uses Green Tea to give you the right amount of caffeine with out having to worry about the crash filling a soda or energy drink would cause.
Best of all you do not taste it, only the fruit! Yes I did say fruit.
In one can of V8 V-Fusion +Energy, you are getting less caffeine then a cup of coffee though it does not lose the ennergy nor give you the fall back when it wears off for really it does not.
It also has one serving of fruit juice and one serving of vegetable juice in each 8oz can.
A six pack of these yummy drinks is only three dollars and it is a must try.
THey are grate when you are on the go and need a quick ‘pick-me-up’.
Zevia is my favorite, but it is -HORRIBLY- expensive compared to like… kroger brand soda.
The best thing you can really do is try to weed out soda all together. Your body will thank you. Unless you replace with coffee, like I’ve been doing. Then your body will be PISSED
