Hi Heisenberg,

This is just a shot in the dark, but I sometimes notice that when I am feeling anxious about nothing at all, e.g. meeting someone that I know well and there is no reason to get nervous about, then it's because I have caffeine in my system.

I also think that coffee makes post-concusson symptoms worse. it seems to bring on the same sort of headache that I get because of PCS. I didn't get this before when I drank coffee, so I thought that it might be worth suggesting that you might want to rethink how much coffee and other caffeine sources you are able to tolerate. It might not be the same as before you got PCS.

I should add that I don't have anxiety attacks, so my set of problems are different from yours, and I am not suggesting that giving up caffeine would be an end to your problems, but I just thought that it might be something that you could try and see if it makes any difference.

Good luck.
