We've had things happen with our daughter that feel like flashbacks too. It makes me think that Singulair pushes certain people over the mood swing/sleep disturbance/anxiety edge who may possibly be a bit closer to that edge anyway. That it why it is such a dangerous drug for a significant part of the population. Try not to make too big a deal about last night with your son; it is probably an unwelcome 'blast from the past' rather than a new trend. Our daughter seems to act in ways similar to her Singulair days when she is TIRED. Good luck.
Well one of the things we told the reporters last night was the "learned behavior". They act a certain way for so long, all of our cells have memory and will revert back to their old ways sometimes. Maybe it is the unconcious learned behavior that has made your daugther, and flindy's son react that way, like you said when they're tired.
My son has been getting better since stopping Singulair but does tend to revert to "Singulair behavior" when tired too.
