Enzymes/ CEASE therapy anyone?

Hello, I'm wondering if anyone else has tried homeopathic CEASE therapy or Enzyme therapy? My son is rising 4, and is having assessments for ASD. So far the paediatrician at Child Development says that he is not ASD, but CAMHS, who have seen him at the centre with me, and observed him in school think that he is ASD. This has been going on for many months now, and we are getting nowhere as the professionals just cannot agree. All the traits seem to have grown in him since the age of two and are getting worse and worse all the time. I cannot sit by and see him withdraw further from life, with no support from the health professionals, so have decided to try CEASE therapy and Enzyme therapy. I just wondered if any other parents had tried either and what results (if any) you noticed please.
