The other day I almost drove into oncoming traffic after having 1 cup of coffee the day before. I couldn't believe what had just happened and it was good that the other drivers realized what was happening so I didn't endure another brain injury in the form of a car accident. I have been noticing that caffeine especially, while working more or less as normal, causes me great problems for up to a week after I drink it.

Now that I have finally quit caffeine entirely I have noticed a big improvement in my TBI symptoms. I can now smoke pot without experiencing anxiety and I am also interestingly able to drink moderately without problem. (I have not drank in almost 2 months and was curious to see what would happen, and was pleasantly surprised when all seemed fine.) I am sleeping better, focusing better during the day in general, and am having fewer problems reading and comprehending text. I am additionally not having spells of crying, depression, anxiety, and other problems for days after having moderate amounts of caffeine. My headaches have improved overall and are less frequent and intense.

I am interested to hear from others who have had problems specifically with caffeine after a concussion. I want to hear about your experience and how long your problems lasted, what problems you had etc. It would be nice to be able to just have coffee again without feeling terrible for days.

I am also interested in hearing about any research which might explain why these problems happen. Caffeine blocks adenosine receptors and as I understand it adenosine is involved in TBI healing somehow but it is not clear to me exactly how.
