Hi Elizabeth,   Many Thanks for your answer.   Yes Louis is on a gluten free, casien free and soy free diet. Which is very beneficial as I do see results from this and if he eats bread with gluten in it by accident. What a nightmare so although I have had Louis tested for celiac allergy and he does not show allergic to it, he does have an intollerance to gluten which is sooo visible by his behaviour. Thats enough evidence for me.   Louis tests positive to allergy (IGe) for the following   Peanuts milk soy almond egg white   We avoid these things.   Louis takes melatonin at night (fantastic sleep aid but I see the benefit from the anti oxidant properties in this also.   Louis takes ALC (Acetyl L Carnitine) NAC (N Acetyl Cysteine) and EFA's every day.   I see a positive result with these. But I have been listening to so much research regarding yeast and gut issues. That I am looking into the probiotics and the benefits to these to restore the natural flora within the Gut as really smelly stools often can indicate that there are imbalances with the gut flora. Etc   I appreciate your help and advice.   I will research and look into finding others who can help.   Amy
