I've come to know it's not always easy... Sometimes there is pain. And now there is literally a device that is a throwback to the days of old fashioned negative conditioning... It's a device that will shock you when you do something you don't want! They claims it's effective in days... Even hours... As your brain begins to associate habits with pain instead of pleasure.
You usually have to shock yourself! So I wonder how the wearer convinces their brain to keep pressing the shock button? And... Why wouldn't the wearer just buy a .10 cent elastic band and snap their own wrist with it?
