Sometimes, I get anxiety at work, and I think it might be because I drink too much caffeine.
I'm  sorry to hear that. I get anxious at times as well but I am not a heavy coffee drinker. I may just be paranoid.
Caffeine can be good for memory, but I think it might have more negative effects that positive.
I was just reading something about the pros and cons of caffeine. The article agreed with you that there are many negative effects and that moderation is one of the best ways to keep them in check, if possible.
How often do you drink caffeine? Do you drink any soda?
I don't drink caffeine every day I think, so a few times a week usually. I drink soda pretty rarely as well so a few times a week.
What do you think of energy drinks? They are similar to caffeine in that they can provide mental and physical stimulation.
I've tried a few of them like Monster, I think I have enjoyed some and that I do not like the taste of many of them on the market these days. I would probably prefer coffee to them.
