I forgot to mention in my earlier account of Margaret's apomorphine trial, that domperidone was administered for about a day or so before the trial began. We were told that this was done because apomorphine can cause severe nausea otherwise. It appeared to work; in the trial, she was completely free of any such discomfort. Take Care Mark.
