Pullups symptoms and conditions

Both my son and I were on Singulair. As of Sat March 31st we both stopped taking it. My 6 yr boy has been on it for apprx 3 1/2 years for allergies along with nasonex and claritin when needed. He started pre k after being off the singulair for the summer. His first 3 weeks of school had no complaints. 3 weeks into school he started singulair and teacher immediately noticed the difference and brought it up to dr's who said it had nothing to do with his behavior. Over the years he has experienced, problems with excess urination after taking dose at night causing exploding pullups.. changed to day time and that helped somewhat. nightmares/ hyper /moody, irritable, leg pain, stomach pain,angry outburst (he says his brain made him do it), headaches, stuttering,sinus infections that he finally had his adnenoids removed in Feb.. He started kindergarten last Sept and it has been a nightmare..I tried to take him off Singulair in Oct but due to his enlarged adenoids his allergy symptons became so much worse I put him back on. The last few days where up and down as the Singulair was coming out of his system but I was seeing improvements.. Well I decided today to remove him also off the nasonex as I have read similar side effects about the nasonex. He had a pretty good morning today and went to school and came home for the FIRST time all year with smileys for the entire day!! I am overwhelmed with emotion! So happy that he is coming out of the fog and guilt that I have been giving him this medication and didn't follow my Mommy instinct to stop it years ago! I had side effects as well to the point people were telling me my personality had changed. I was irritable, short of patience and having alot of headaches. The last few weeks I was having days of depression and crying over little things especially with the stress of what my son was going through.... I am also coming out of the fog and happy to be back!
