as a doctor with adhd who treats kids with adhd ill add that the only time i agree with med holidays is for kids who dont do good enough catch up eating when meds wear off and do their best eating on med holidays and were otherwise struggling to get good growth also sometimes ill do it for blind trials to school if its a kid with less of a clear response to a med     i also do the wake up thing especially with vyvanse where it takes a bit longer to kick in my meds and a glass of water are on my bedside table so that i can force my sleep drunk first alarm self to reach  over and force down my meds
