Singulair Stuttering, Acts of Aggression, Stammering, Honor and Glory, Outburst

STUTTERING, STUTTERING, STUTTERING!!!!!!
Please help! Anyone whose child has experienced stuttering and/or stammering on Singulair please email me (just click on my "nomeds" name and it will take you to an email page).
My 3 1/2 year old son was on Singulair for a year and a half. He started stuttering 2 months after taking Singulair, however we did not make the connection until reading this site. When we took him off the Singulair it seemed as if the stuttering was completely gone within days. Unfortunately, it seems to come and go now. Can anyone help me with this?
Also, we noticed a HUGE difference in behavior, outburst, and acts of aggression. Like so many other parents have said on this site, I have my little boy back now!!! Honor and Glory goes to God and much thanks for this site!!
