I guess I shouldn't have worried much. Ya know that whole sedating thing might be a good thing right now. There are times I really think my kid is possessed and I would love to beat the evil spirits out of him. (not that I ever would) I must say he is sl calmer. The thing I don't know how to respond to is his need to fight the sedating effect. He does everything in his power to stay awake until he is miserable along with the rest of the family. He gets soooooo loud and is incredibly irritable and becomes teary and overwhelmed with any correction. Ohhhhhhhhh what did you say the major side effect was? lol thanks for listening to me gripe
