Thanks James!
My son actually thinks that it's getting better. It's interesting how he used to be reluctant about taking this alternative approach and wanted to get the antibiotics from the doc.
The diet is mostly vegetarian with some kefir and a little bit of cheese occasionally. He thinks that it was the stress that caused him problem. Then he is in luck. Summer is here.
They did a study a while back on college students suffering from acne. They found that the problem was not from the stress affecting hormones or anything like that. When they were stressed the students would be touching their face more in their sleep contributing to the acne.
Maybe washing his hands and face well before bed can help.
