Hi Kajong,
Sorry for the late response. From the guidebooK:

Listen to Session A one day and Session B the next day for at least a week.
Then listen to each session once or twice a week until you reach your
ideal weight.
Listening more often will not help change your weight faster. The relaxation
session, however, may be beneficial.
Once you have reached your ideal weight, you will maintain it naturally as
you enjoy an optimal balance in your diet. Feel free to revisit the sessions
whenever you feel you need a boost.

Enjoy!
Patrick
