My husband just got put on this medicine. He has tourettes syndrome, ocd, and adhd. He works a full time job on rotating shifts and is concerned that it might be making him sleepy. The medicine he was on before gave him energy and made him able to concentrate on one task at a time. The dr wants him to try this medicine and on the first night he seemed out of it and very tired. That could have been lack of sleep also before taking it. So anyone had any experiences with any side affects? Thanks!
