I bought a "fidget cube" off Amazon recently and I'm finding it so beneficial that I wanted to share it with everybody. I was a smoker for 15 years, and if I were still a smoker I would find this so helpful in quitting. I use it to stay calm when talking to my mom on the phone, and I use it throughout the day. I would think it could be a helpful tool for alot of addictions. My husband has one too, and he also has this spinner thing that he likes, too. Just thought I'd pass that on - you can just go to Amazon and check them out. Let me know if you have any questions.
