My son is having the problem of vomiting since last 4 years. He is now 6 years old. He has unique pattern of vomiting. Many a time he will wake from deep sleep in night and cough persistently and then will finally vomit the food he ate. We have noticed many times he have the vomiting sensation in mouth and even he vomits after having some pucks. We have taken the homeopathy treatment as well for 6 month. He is fine, till the time medicine is continued. Once we stop the vomit cycle repeats. I wonder if there is permanent cure and whats the reason behind this persistent vomits.
