If you have difficulty controlling your cravings for junk food, then it might be time to consider a bit of self-administered shock therapy.
Amazon is selling a bracelet that claims to help you break your bad habits by administering a 350-volt electric shock every time you reach for the biscuit tin.
The shock can be self-administered, using the button the wristband, or it can be activated by an external sensor connected to the Pavlok app on a paired smartphone.
Your friends and family can also download the app to keep track of you, and if they see you've been eating too much can zap you remotely.
It doesn't just work for junk food, but can be used to break bad habits ranging from smoking and nail biting to oversleeping, according to Pavlok.
As well as delivering an electric jolt, the bracelet can also beep and vibrate.
So if, for example, you want to wake up earlier, you can set an alarm within the app. Pavlok will vibrate gently around your wrist to rouse you, but if you ignore it you'll be zapped with an electric shock.
You could also link it to your bank account, so you get a shock for exceeding your spending limit , or use a GPS sensor to deliver an electric shock if you don't go to the gym .
"Pavlok allows you to speak your reptile brain's language by adding an unpleasant element (a safe and harmless 'zap' of electricity on your wrist) to what you have been taught to love (your nasty lingering habit)," the company states on its website.
"Quickly conditioning your mind to associate an 'unpleasant' feeling with your bad habit… and stopping it all together."
The Pavlock 2 bracelet comes with a choice of colourful silicone wristbands, and a micro USB cable for charging.
The battery has the capacity for over 150 tiny jolts on a single charge.
Inventor Maneesh Sethi told ABC News that while it isn't as powerful as a shock from a tazer, it still delivers enough voltage to make you jump.
"It feels like if you were to touch a doorknob after rubbing your socks on the carpet," he said.
The Pavlock 2 bracelet is available on Amazon.co.uk for £193.62, plus £3.67 UK delivery.
