I was on Depakote CR for 2.5 weeks 1000mg. When I contacted my pdoc she and told her the side effects: (lethargic, dizziness, tired, seeing double), she told me to stay on the medication. I had difficulty at work so I dropped myself down to 500mg (even had trouble with the 500mg trying to work). I am now seeing a new pdoc and told her the story. She is weaning me off the med, I am now taking 250mg for the next 4 days and starting Ripersdal (however you spell it).
