Some interesting suggestions .... but in the end I succumbed and I'm now sipping that second cup of coffee, I will try to drink something for the next drink.
Squash I don't like - or at least the orange, lemon, blackcurrent ones, though I have got a mint cordial somewhere and I quite like elderflower. Lemon tea I do like .... too much, I was going through half a lemon a day when I last had a major fondness for it, and it gave me unpleasant side effects, but maybe I could allow myself one a day? And I do like Earl Grey and have some in the cupboard so maybe that's the next drink of the day.
There is something very comforting about the silky coffee drink, that I find hard to resist but as I say I think I have too many.
