... high of 800 mg/day. She was also on 10 mg/day Lexapro for the last year. She began having involuntary movements in the eyes, mouth, neck but the Drs said it's not a movement disorder. EEG confirmed it's not seizure activity, but we have no diagnosis and no treatment after six weeks of distress. My daughter is also non-verbal autism which makes it more difficult. Has anyone experienced similar issues?
