My daughter takes 300mg oxcarbazepine 2x daily. She got sick for a few days so her meds got out of sync because she couldn't keep anything down. She is has been over that for a little while but it's like starting all over again on her meds. The biggest side effect she has is vomiting. It will last most of the day for her. She will start to feel better at night but the next morning it starts all over. I am wondering is this going to go away or should we look for something else. I hate to change meds again when we have found something that works for her bi-polar symptoms.
