Here I go again, unable to fathom my son's suicide, I'm wondering about things again. Could it be possible that maybe some of the side effects do NOT go away with the discontinuation of Singulair? Can certain effects stay with you and do permanent damage? That is if you're on it long enough. A.J. was on it and off of it, (on it more than off) for 9 years. I never caught on. Now that it's too late, and I've learned about this stupid drug, I've got to ask every question that comes to mind. I, too, have asthma and I am tempted to go to my own doctor and request to be put on it just to see what happens to me. Right now I take Advair and I see where it causes problems that are equally as bad for some people as Singulair. I'm one of the lucky ones. It does me well. My depression comes from the death of my son.
