Hello Chris18
Yes, Ive seen pois behavour pattern in my father. Some days he's very fresh and friendly , while some days he's totally stressed and at that time he drinks and smokes a lot, he gets very sensitive to people's behavior and he suffers from depression. He has been taking depression medicines since about 10 years and still is in depression , not cured. Before my birth too he was smoking a lot, almost 40-50 cigarettes a day, I think this may have caused some kind of genetic change in me. I am still not sure whether he is a POISer or not, But i am a POISer .
