I had a post on Jan 29th about my daughter's symptoms being on Singulair.We have taken her off of it, and unfortunately had croup and wheezing bad enough,about a week after that she needed medical attention.However,she is completely back to normal with her behavior,and she is not having anymore vivid dreams,just seems happier as well.We will continue to keep her off of it,but I am going to try and seek a more natural solution for her asthma.
