Lily, he displayed No symptoms at all. Except depression, but there was MLC at the same time. He is active (works out) and hikes and bikes all the time too. He doesn't smoke or drink, doesn't like to drink. He has occasional insomnia. No bugged out eyes or "moon face" etc. He eats very healthily. He's not tired all the time, just the usual tiredness that comes by 9:30 pm when you get up at 5am each day. Lisa
