My Mom got me a box for my birthday. I finally opened it up last night, because my cold has let up and my taste buds are working again. WHOA, Dude! Is there enough caffeine in there??? I think if I had made the tea in a larger mug I would’ve been found clinging to the ceiling with my fingernails. I forgot about that affect. I also forgot that you only need to steep this for a minute or two or it will get very bitter and load even more caffeine into the tea.
