Why doesn't coffee affect me?

Question

I can drink caffeine all day in the form of coffee, sweet tea, coke... whatever, yet I don't get the energy or the jitters that everyone else seems to get when they drink half as much as I do. I can wake up, drink a glass of tea, go to work, drink a cup of coffee (or two), go to lunch, drink another glass of tea and I'll still feel sluggish. Am I just immune to caffeine?

I don't drink it like that EVERY day, just sometimes. But I do have sweet tea or coffee at least once a day. I can have tea or coffee right before bed too, like another answerer said, and it does nothing.

Answer 1

I guess since we are all different things affect us all differently.

Before I switched from Diet Coke to caffeine free Diet Coke I would often take a can of Diet coke to bed, drink it and lay down and go right to sleep, it had no affect on my sleep.

I switched to Caffeine free Diet Coke just to get away from the Caffeine for health reasons (caffeine is hard on the kidneys) I had no "withdrawals"

So to answer you question I don't think it is a matter of being "immune" it just does not affect on some people.

I remember my grandmother would not drink coffee after NOON!
Otherwise she said she could not sleep at night.

Answer 2

It doesn't do anything to me either. I can have a coffee or tea right before bed and still sleep like a log. I don't drink the stuff all day long either so I can't possibly be immune to the caffeine. Sometimes I wish it did especially when I've got things to do. Maybe it'd get me up and going. LOL

Caffeine is a drug. If you take any drug long enough you will grow immune to it. If you don't need it why do you drink it so often? Try not drinking it for 3 days and see what happens. If you start to get headaches drink the caffeine again and then ween yourself off of it.

You have built up a tolerance. It takes a ton of coffee to affect me. I drink at least 6 cups a day. If I go without, I get horrible headaches, nausea, etc. If I want a real jolt, it takes about 4 shots of espresso to do it. Anything less and I don't feel it.

It doesn't bother me either, I can drink coffee right before bed and it has no effect what so ever. We must be immune to it or just used to it.

Ah... the question is can you wake up and not drink any caffiene drinks for a day.

Your body has gotten used to the level of caffiene you're taking per day.

I bet if you started drinking decaffineated drinks, you'll notice the difference.
