Welcome, yes it is completely normal to be nervous. The band does not do all the work for you, it is a tool (a powerful tool) but still a tool. It won’t choose you food for you, make you exercise, prevent you from eating slider food ie: creamy, buttery mashed potatoes, and Ice cream lol. It won’t deal with your self-esteem, body image and food issues. And to be honest for some people it just doesn’t work for various reasons. But some have great results. I’m down 24.4 lbs since banding March 7th. Good Luck to you on your journey!
