Yes, I did it! A Detox from WhatsApp. I have just moved from Brazil to Spain. And I decided to leave my Brazilian WhatsApp number behind.
You might say: but you could keep that Brazilian WhatsApp number. Then you could change your WhatsApp number (and use the feature to inform the change to all your WhatsApp contacts) once you got your Spanish mobile number.
I know. But I wanted the detox. It was only a few days and it felt great! I was not tempted to look at one of those numerous messages from all those groups and contacts.
Give it a try. Take a few days off. Just uninstall the app for a few days.
