We never use drugs only fish oil for the brain and evening primrose for our sons asthma. My daughter does a massage technique called craniosacral. This technique is suppose to release mental pressure and hundreds of parents with autistic children swear by it for a solution to the head banging. Our son use to band his head. We would grab him up and massage his head. Little did we know there was a name for it. There's more to it. Look around and call. Talk to a personal massage therapist.
