i don't know what to tell you about the delayed (two months in) nausea. I came here looking to see what experiences others have had starting Vyvanse. My almost 9 yo son has been taking Metadate CD for almost a year, but we stopped over the summer. He seemed to do well with it during school, but at home (without the structure) he was very "bored" and moody much of the time, almost to the point of tears. The dr recommended trying Vyvanse (30 mg) as an alternative. We tried it one day last week and about mid-day he became very pale, clammy and nauseous. He then vomited 4-5 times throughout the afternoon and evening. We wondered if it could be coincindence or the med. We rested for a few days and tried again yesterday. In the meantime, I'd had a very stressful public outing to the dr's with both my ADHD boys. He was resistant to trying the Vyvanse again, but I told him if he was to go out shopping with me again, he had to take his pill. He did take it yesterday and was quiet as a church mouse, but very sullen, depressed-acting. He didn't eat much, and in the afternoon driving home he again started vomiting. He vomited several more times into the evening. I won't have him take it again. We're not sure where to go from here. He wants to begin school (two weeks) without meds. I may have him try it and if we run into concerns with the teacher, we can go back to Metadate CD just on school days.
