I just heard about this from my mom this morning. I've been on Singulair for 4 years for allergies. I'm 23 years old. Over the last several years I have had many nights that I went without sleep. I have gotten severely depressed and on the rare occasion that I drink more than a couple drinks, I have had insane mood swings. I have had horrible anxiety and I have gone from an honors to student to being on academic probation. It has really helped with my allergies, but I had gone through hell the last few years and I've been borderline suicidal for a period.
