While CBI can be both challenging and demanding for the teacher and the students, it can also be very stimulating and rewarding. The degree to which you adopt this approach may well depend on the willingness of your students, the institution in which you work and the availability of resources within your environment. It could be something that your school wants to consider introducing across the curriculum or something that you experiment with just for one or two lessons. Whichever you choose to do I would advise that you try to involve other teachers within your school, particularly teachers from other subjects. This could help you both in terms of finding sources of information and in having the support of others in helping you to evaluate your work.
Lastly, try to involve your students. Get them to help you decide what topics and subjects the lessons are based around and find out how they feel this kind of lessons compares to your usual lessons. In the end they will be the measure of your success.
