I don't mind the minty taste to start the day but if I am staying at a guest house or hotel the minty taste in the mouth with orange juice and breakfast (which I wouldn't normally do at home that early) can be a bit of a shock to the system.

The worst tasting toothpaste for me was the Punch and Judy children's toothpaste flavoured banana or strawberry. I haven't seen it around lately so I am assuming that it has either been taken off the market or changed slightly to discourage children from swallowing it which really is a good thing to do.
