My 7 yr old son has been taking Singulair for appr. 2 yrs or more. He has had nightmares frequently throughout the time he has taken it. I blamed it on possible too much "junk" food. He has also had meltdowns that can become out-of-control. I wonder id Singulair could be playing a big part in this. When he's having a good day, he is so happy and loveable and very sweet. He can be this way after he comes out of the meltdown as well.
