I posted a paragraph at the end of June, after my son had been off Singulair a short while, but enough for me to notice the difference in his behavior. He's 11 and became so aggressive on Singulair that it was affecting the whole family. Well, we took a vacation with my family and they mentioned, on their own, that they saw a change in my son. We were not talking about singulair or anything like that. They just said that they saw a change in him. How nice!!!! I also realized that, finally, he was not having any more nightmares. His behavior changed immediately, thank goodness. The nightmares, well that took a little longer. I can live with that! Hang in there everyone else!!!
