Singulair and lack of motivation

My son 10, has been on Singulair since he was 4 yrs old for Asthma and allergies. His last dose was 3/26/08. He has always been my emotional child, he is 2yrs older than this younger brother. Some of his side effects included headaches, stomaches, leg cramps, emotional breakdowns, major mood swings, crying outbursts over small situations, night sweats, lack of motivation, weight gain, ADHD, wishing he were dead and the list goes on. His younger brother has always been involved in sports but he was always too afraid he would get hurt. This medication has robbed my 10 yr old son from 6 yrs of his childhood. Since he has been off Singulair he feels motivated and looks forward to joining the football team his younger brother plays for. I look forward to meeting this new young man who for so long has been hiding behind this so called allergy medicine. I am so thankful to know that my son can look forward to a bright future without these side effects. God Bless you all who are going through this as well.

My son is 17years old and has been taking sigular for 5 years due to allergies and a minor asthma condition, I am also seeing many of the side effects. The major ones are explosive anger, easy frustrations, laziness/lack of motivation, leg pains and cramps in legs, and when he sleeps it is almost impossible to wake him up in the AM. He mumbles and says OK I will get up , then after 15-30 mins and he is still in bed and constant attention by me to wake him, he finally wakes up and says, why has no one tried to help get me up and he is very anger. He has raised in bed, screaming, and punched at me during these 15-30mins, to later say, NO way I didn't do that, I don't remember. He seems to be in a trance!. I have been struggling to figure this out for 2 years now,

I do agree that I saw an easy going kid turn into one filled with anger and frustrations for no real reasons.
