The side affect that concerned me was the eating. Sometimes he would eat until he vomited. Apparently,
risperdal turns off the switch
in the brain that signals fullness. His eating was becoming a real problem, so we asked about Abilify. He's been on that a good while, and it works. He's taking 5mg 3 times per day. It's not perfect, but it's better than the rages. I will warn you that it does make him kind of sleepy, but not too bad.
