i am surprised that people haven't commented on my sugar habit with coffee. i used to put like 15 sugar packets in my coffee sometimes. and also when there is a sugar pouring device i usually hold it over the coffee for minimum 20 seconds.
Sugar ruins the coffee flavor for me. If I'm not in the mood for the usual black death I'll put some honey and milk in there, because Trader Joe's forest honey in coffee = teh w1n.
