I am amazed at the stories, but also feel somewhat validated. I have a 10 year old boy who has been on Singulair since he was 2. My husband and I often wondered why we had such a grumpy boy? He had such horrible tantrums until age 6. We often thought of sending to someone for anger management, but really it was the drug doing this to him and I'm the one who continued to supply it to him. What really makes me sad though, I don't even know what his personality really is-it's been altered for 8 years. I can't wait to get to know my real son...
