Tell us about yourself!
The odd reason is not so odd, its probably MSG, monosodium glutamate, the artificial (uh hum 'natural') flavoring/preservative added to chai pods. It alters your brain chemistry, making you crave more of it, while it fries the nerve endings in your brain. Keep enjoying your afternoon chai with ORGANIC chai that includes ORGANIC spices or ORGANIC essential oils, and brew with filtered water. Bon Apetite'!
