i have been taking singulair for the last 9 years. i started taking it when i was in the 6th grade and i am now in my second year of college. i have had suicidal thoughts since the 6th grade and have gone through some periods of severe depression. i was hospitalized this past fall for an attempted overdose. I've never been able to figure out what causes all of these horrible thoughts, but i keep trying to fight them back. in the fall, i just couldn't battle anymore. i never ever would have linked any of this to the singulair though until my sister just told me about the stories being published in the news right now. if it's true, the timing of the onset of my suicidal thoughts would make a lot of sense. that bad thing if it's true, is that it really does work extremely well for asthma so now I'm going to have to find another medicine because i don't want to continue taking Singulair if that has been affecting my mood.
