Could it be something other than the caffeine causing this. Most of the teas I have had effects with are at least 1-2 years old. Could it be because they are too old? I think they are stored well. The puerhs are not as they are being stored for aging. Could old teas bring out more caffeine in the leaves? That doesn’t make sense. This happened all at once. I am both puzzled and concerned that I have developed a real caffeine sensitivity. That would be real bummer.
