Good question. I want to buy one to check it out because right now I'm on full liquids and found myself talking to my son while eating a pudding and smashed it down. I'm thinking something needs to help me control the speed in which I eat.
I got a cheap pack of 10 of them at Walmart. My surgery is in a week, so I've been practicing with them and have found it really does help me slow down. Let me know how it works for you!!
