The solution is short, sharp and extremely effective. All you require is complete reliance & faith on Allah (SWT), consistency with the program, as well as patience and determination.
In our experience the people who get cured most efficiently if not in the first session are the ones who's Aqeedah (Islamic Creed) is correct & they have a firm understanding of Tawheed (Oneness of God). They are the people who not only have complete Tawwakul (Reliance on their Lord), but they also implement the religion (Islam) to the best of their ability & are wary of committing sins.
