The biggest issue I have with incense is that people burn too much it at one time or burn a whole stick/cone in too small a space and the smell becomes too strong or there is so much smoke it seems to coat everything in the room including people. My bed room is small and I'll burn 1/4 to 1/2 a stick at a time to add a slight change in the scent and atmosphere of the room but I don't want to bath in the smoke/odor.
