I don't believe I've ever seen Q Tonic in Europe.
One thing I didn't realise is that Schweppes Indian Tonic isn't commonly available in the USA. I didn't know Americans were drinking a different version to the one we have.
There's a very interesting comparison of many different tonic waters here

I do agree with their rating of Fentimans but then, I do have a strong fondness for Fevertree, but that's because I see it as a sweetened soda treat more than as a mixer (haven't been able to drink much alcohol for a few years and need to wait a bit longer until I can start again)
