I have Barley Cup from Holland and Barrett in my cupboard, for when I fancy something different. It's certainly not my 'go-to' choice for the mornings though! Even after years of drinking decaf I prefer the aroma and taste of coffee to help me start the day, even though I don't get a buzz from it 
not a great one for gadgets but some I have bought


if you enjoy rushing to the loo all the time.
