sleeping was a huge issue for my son,like he forgot how to fall asleep,got so bad we had to see a sleep doctor,and reset his internal clock,which was only a temp fix as he was sstill taking singulair,now he is off singulair things are so much better,but we had to retrain his sleep and he is 14 years old .......crazy
My son would have night terrors and fight sleep all the time. He would cry because he was so tired, but just couldn't fall asleep. He was on Singulair for 2 years and we just took him off last week. I have noticed a significant difference in his behavior and he has been sleeping 10 hours a night and a 2 hour nap in the day. Keep a close watch on your sons patterns while on this drug, especially behavior changes. I thought it was terrible two's and horrible three's but it was a reaction to Singulair. Good Luck!
