It works like a charm.
Do this out loud:
Say your name. Say what time it is. Say where you are.
It's simple enough, but it's always good to get a reminder.
Bringing yourself back into present time this way means that you aren't thinking about how you're going to lose that extra pound or two. It means you're not going to be able to worry about why your next paycheck has been spent for two weeks already. It keeps you from thinking about anything else.
Even if it only disrupts your thought for the time it takes to say it, that can be enough to help you get out of the constant worry that's going over and over in your head. Like the way you can use jumper cables to start a car so it can drive off in a completely different direction.
It's good advice to remember occasionally.
Breathe, and present time yourself. You will be glad you did.
