his initial ocd symptoms only came on after having a course of antibiotics. we feel that it is his gut that is creating his issues. it was not only the antibiotic issue we encountered but also that he had had his initial symptoms(frequent urination) after eating at an event-wheat, dairy, sugar, strawberries. we were not sure what was the trigger but it happened within about 10 min and lasted for 6 weeks. so we could see his symptoms were triggered by food and for us with antibiotics. due to his rapid decline with every small sore throat etc i researched natural antibiotics and found vit c to do the trick for him. the gaps diet works at the level of healing the gut, immunity, etc etc. this fit with my understanding of things and worked for him.
today... 10 weeks from his regression... i saw a small reduction in symptoms. not sure but fingers crossed that this episode may be settling down again.
