My addiction

This is taking over my life. I HAVE to have these - daily. I eat about one box a day, and at my desk I currenly have 3 empty boxes, and 3 more empties in the car, as well as partially eaten tins in my purse, beach bag and computer bag. I am NEVER without these, and have occassionally lost track of how many in a row I've eaten. This leaves me with a runny nose and watery eyes, and my sinuses burning. I need to start buying these in bulk, because I will surely go broke otherwise...

What is this truly addictive substance?
