My autistic son of 17 years was percribed Risperdal which he took for 3 months. During that time he balooned in weight and wanted to sleep all the time. We told his doctor that because we did not see enough benefits and my sons self esteem was very low, we wanted him to come off it. He has been on concerta XL for sometime and it calms him down but makes him aggitated at night. I have been reading about Depakote. Can anyone tell me what they think about it.
