yes. I am rediculously addicted to ice. My company has an ice machine that disperses the ice where it is nearly like sonics but softer. I buy about 2-3 bags of ice per week. I eat ice ALL day long. I have had people tell me I am anemic, its pica, phycological, etc. I dont snack nearly as much nor do I eat as much. I have noticed I havent lost any weight... Make sure you tell them at Sonic to give you "freshly made ice. The bag does refreeze. A little water will ease the hardness.
good luck!
