I feel I've gotten more help from Dr. Teitelbaum's book than from the doctor's I've seen. Their staff is also very helpful if you call or e-mail a question. It's my opinion that Dr. Teitelbaum may be an even better psychologist that he is a doctor. The only drawback that I see is that Dr. Teitelbaum's solutions seem to be quite expensive. The average person with a family using Dr. Teitelbaum's protocol would have to work pretty long hours to pay for the treatments and of course, the average reader doesn't have the capacity to do that or they wouldn't be drawn to the book in the first place. Overall, I think it is a very good book and I do use some of Dr. Teitelbaum's products.
