my 8 yr old daughter just got switched from focalin to vyvanse 40mg and not two hours after she took it she was in class and got sick she cant hold down her food cuz her tummy hurts. granted she cant take pills so i have to open then and give then to her as a powder her doc told us it was fine i dont lik that she is not holding down her food.. i always make sure she has a good meal in the morning befor she takes her med. just wondering if anyone else had this problem and if so if their was anything u did that helped them hold down the food???
