Hello wolfie205: Honestly I don't know what it is that was going on here. What I do know, from personal experience, is that high levels of anxiety can cause a lot of strange symptomatology. So what occurs to me reading your post is that this experience is perhaps a "heads-up" telling you that there is something going on with you that needs attention... probably with a mental health professional. Personally I don't believe caffeine alone could be the cause of something like this. Of course, if you're highly anxious / stressed out to begin with, & then you're consuming large amounts of caffeine as well, that's certainly not going to help. But I don't believe you can attribute what you experienced to caffeine alone. I wish you well...
