Thank you so much for taking the time to answer me back.
The zapping is going great!! I’m feeling more energized each day!!!
It is amazing, I feel more alert and focused!! How often should I zap after the 21 day ?-M.M.

We recommend you use the zapper every day, and encourage that for everyone. See these videos:
