I tried Camomile tea for the first time a few days ago and didn't really notice any difference in anxiety/relaxation levels.
This morning, I drank a cup before my driving lesson. In previous sessions I have spent the entire lesson sweating, panicking and tensing up which makes driving considerably harder - today it was completely different! I reacted quickly to hazards without fear, I even enjoyed the experience!
I am also taking 20mg Citalopram, I have been throughout my course of driving lessons (12 hours so far), whether that helped I'm not sure. I'll definitely be drinking more of this though!
