Clients who are resident in Spain, and visitors who are not on a tight time schedule, usually prefer to spread the sessions over up to 2 weeks. It is also possible, and now quite common, for clients to fit the sessions into either a four, or ten-day programme: although the benefits and results are the same, this does place the client in a more intense situation, requiring attendance at the clinic either daily, or on alternate days, in order to complete the treatment.
