Hi, glad Nytol are working for you, anxiety is awful and difficult to explain to ppl if they have never had it.
I tracked down a tea I used to drink (Nytol did not work for me, also tried Diazepam which was ok, ignoring the slightly psychotic feeling I got from it!). it is not readily available here anymore. It is Celestial Seasonings Sleepytime Extra. It contains Valarian which is a well respected and ancient 'relaxer'. It is only a couple of quid so worth a try. Tastes mostly of spearmint and only a little cammomiley.

Like I say, worth a try and this is one of the few places that carry it now. Has to be the 'extra' not the normal.
Good luck, and hope it sorts itself out for you.
