How much coffee where you drinking? Seems like kind of an extreme withdrawal, but I am willing to guess some people are more sensitive to that than others.

I have not really experienced more anxiety if I don't drink anything with caffeine...though when I am drinking coffee or other beverages with caffeine regularly I will sort of get a headache and maybe a bit irritable without it.

As for never having caffeine with anxiety, I find that a little bit extreme I have generalized anxiety disorder and PTSD and still like my coffee, tea and occasional energy drinks/mountain dew. I will avoid it if I am feeling particularly edgy, but there have also been days where I would have had a very hard time getting my day started without some caffeine since much of the time I don't get enough sleep.

Basically though caffeine is a stimulant so it can sometimes contribute to anxiety symptoms such as increased heart rate, anxiety and stimulants effect the body kind of similar so that is why caffeine can be bad for anxiety...but yes getting dependent and then going without it is possible to cause anxiety due to the withdrawal.

sometimes though it seems a lot of people forget/ or simply don't know caffeine in their coffee, soda or whatever is a rather addictive drug...then wonder why they get a headache if they forget their morning coffee.....speaking of which maybe I should have some iced tea or coffee or something.
