I have. I won’t go so far as to say massive disappointment but I was hoping for better, in the end I added guarana to my own freshly ground coffee beans for a while but I got bored of it in the end and just went back to drinking regular coffee.
I’d forgotten about guarana, tempted to get some powder again and try it in coldbrew.
Lies are clearly a lot of fun 
I thought it was a little bitter…and lacking depth…it is made by Percol…and I quite like Percol coffee for an instant brand.
Edit: It appears the forum discriminates against certain emoji’s. Not very 2018.
I’ve just tried to reply “OK” and I got a message “post must be at least 10 characters”.
It looks like your issue is that the pure text form of the the emojis you used, wasn’t long enough to qualify as a sentence under that general restriction.
You sir are correct. Well spotted.
