Ditto on the caffieen and even nicoteen being bad for the anxiety I find in me it brings in on much stronger it it is already there and will bring it out sometimes if it is absent. I am not sure if that makes sense but basically it sends your mind a mile a minute and makes that feeling in your shoulders/back worse. I don't know if you get that one but I do. I stick with lots and lots of water because otherwise I get dehdrated pretty quickly and that makes everything worse as well.
