Can you function without caffeine?

I haven't had caffeine regularly for the last decade. I have a Keurig with the Cinnabon coffee K-Cups, so I'll have one if the mood hits me.
I'd encourage you to try beetroot supplements that help your body maintain its Nitric Oxide levels. That, with some proper hydration and extra exercise, does wonders.

I have eliminated all caffeine and sugar.

Except for 4 x 2-L containers of Mountain Dew (w/real sugar) and several types of candy (mostly Snickers or Payday).

I was assured that there is very little caffeine or sugar in this from a new study fresh off RFK, Jr.'s desk.

I am so relieved to hear what I wanted to hear! YAY!

I got up to five a day of these. Wasn’t too long after that my heart made it very clear that I was pushing my luck.

I run on zero caffeine now. It’s been replaced with rage and tacos.

I drink one coffee every morning and that's my caffeine for the day. Anything more and I am jittery and anxious.

Not very well lol. I am very much adapted to it.

I also drink a lot of diet soda. Not only for the caffeine but also bc it keeps me from snacking.

I have eliminated it completely due to health concerns. I did not like the dependency but I really did not like the heart arrhythmias.

I started drinking black coffee in the 7th grade. Now in my late 60’s I get a monster headache if I don’t get at least two cups early in the morning.

I drink two cups a day. I used to drink much more. I know someone who gave up coffee and switched to Mountain Dew for the caffeine.

Nope

I can function .. I sometimes can't be around other people, but I can function. 😉

Youve built up a caffeine tolerance. You get a withdrawal when you dont have it.

Coffee is just the same as any other drug.

If you stop taking caffeine from any source for a few weeks youl even out. You might sleep for a solid 3 days or so at the start but after a few weeks you will reset and be back to only needing 1 cup a day.

Yes, some days I don't drink coffee or any caffeinated drinks.

I seem to not be able to function at my best without it. when i feel like my energy's gotten a just a little low, immediately get my coffee that i prepare everyday 😭

Yes i can

Nope, coffee is what gets me through the day and has for many years now.

Yes, I don't need a stimulant to get me going in the morning and only drink tea

Yes, I recently quit drinking coffee daily, I have no addictions 😄

Totally..I have no addictions.

Yes. I drink coffee but more for the routine. Not the caffeine.

No, I can go without coffee or anything else caffeinated.
If I do drink some caffeinated beverages usually only two at most.

I can, but I don't like to. 😅

I can but I am cranky

I definitely can't able to function well without coffee

The fact is.that i love everything about coffee.

No, I drink way too much caffeine. I must have it.

Try amphetamines

i can function but wont be in a great mood about it without my coffee and likely dragging ass

Yes, of course.

Well no, not actually.

No
