There's an anti-energy drink with melatonin to put you to sleep:

You could try a ginger beer. They're non-alcoholic, and are more of a strong ginger ale without caffeine. Some brands offer different strengths and some have sugar free options.

mf just want to drink cough syrup for the taste.

I just want to point out that caffeine is an appetite suppressant, so a decaf energy drink might not provide the effect you're looking for.

Take a caffeine free soda and add one of those "water enhancer" things like a propel or mio in a similar flavour. All the overabundance of flavour without the caffeine.

To echo what @ennemi@hexbear.net and @plinky@hexbear.net have said, try making your own kombucha!

Kombucha is tea that ferments kind of like vinegar does; it has lots of live probiotic cultures, plus lactic acid and acetic acid and a couple other things, that give it a strong taste and make it hard to chug. It has a small amount of caffeine in it, but nowhere even close to what an energy drink has. It may help with satiety; I also had a friend who used it to help overcome a dependency on alcohol.

Many store-bought brands have a considerable amount of sugar in them, plus they're kinda pricey. If you brew it yourself, you can control the tea/caffeine strength, as well as the sweetness and tartness (as time goes on, the sugar in the batch turns into acids and carbon dioxide), and eventually you can even mix other stuff like green tea, white tea, herbal teas, or other flavorings in with it.

All it takes to make your own is a couple black tea bags, a little vinegar, some sugar, a large enough jar, some starter, and a bit of patience. You brew the tea, you sweeten it to southern sweet tea levels, you drop its pH below 4, and then you wait. In 8-12 days, the sweetness should diminish to only a faint level.

I recommend at least a quart-size jar to brew it in. If you're interested, I can mail you a starter, I need to start my next big batch anyway.

I've been giving my son my unique blend of caffeine-free NOS energy. Replacing the caffeine with actual NOS. Seems to chill him out if anything.

I don't know and I've asked myself the same question, but I think you should try kombucha if you haven't. It doesn't taste the exact same but it's the closest thing I know of to what you're looking for

Have you tried strong red tea/other herbal teas? They have lots of weird tastes

Also drinking hot water helps a bit more (it feels more filling). Congrats on the gains

Try some ginseng based beverages would be my guess

Hibiscus is awesome. It's zero calories, tastes like juice, and cheap. You can add it to your own homemade low calorie kombucha and you're in flavor town.

man I wish there was a version of the blue full throttles that I could drink a bunch without dying

Might find a diy recipe for your favorite drink online. Leave out the "energy" portions.

Electrolyte mixes maybe? Caffeine free ones might still have other stimulants.

some youtuber called Nile Red made some decaf red bull, maybe that's useful somehow.

Sprite Zero Sugar, it has no caffeine

can you really synthesize the flavor of carbonated water mixed with sugar and caffeine

how many calories are you aiming for btw

There is a juice brand called Fruit Shoot that I love and has surprisingly low sugar and added ingredients (relatively speaking, for the category, still be mindful of the nutrition), yet has very intense flavor.

The green apple one for example tastes like green apple candy, on the level of energy drinks IMO. Maybe you can give it a shot if you can get your hands on a Fruit Shoot

Herbal tea is my go-to for alcohol cravings, might work similarly for food.

There's a near infinite variety as well.

Flavor isn't "intense" like artificial flavoring though, but they can have strong flavors depending on what you're putting in them

Like what is this 'intense flavor' that you're looking for? Because otherwise what you're describing is the worst seltzer flavor imaginable. Guarana flavored La Croix

they still have caffeine but i like ghost energy drinks, they only have 100% daily value of a lot of ingredients that other energy drinks have 200% or 400%. i think the caffeine is still at 200% but idk for sure i don't have a can right now.
