I went to see a dietitian about my son waking on average every hour, having been on a strict elimination diet for 2-3 weeks with no difference to his sleep. The dietician didn't tell me that the probiotic I was using was high in amines and didn't pick up that he was probably having too many amines from other food he was eating. I found out through the facebook group that the probiotic is high in amines. After two days of stopping it, my son started sleeping better. Last night, my son slept for 4.5 hours straight for the first time in 8.5 months. I can't thank you enough.
 
I've spend thousands on specialists trying to find out what is wrong with my son. Through your books and the forums, I've found out more than going to all of the specialists combined - member of facebook group http://www.facebook.com/groups/128458328536/
