My 14-year old ADHD son has 3 main triggers, besides forgetting to take his medicine: sleep, food, and water. If he is even slightly hungry, dehydrated, or tired his temper can go from 0 to 60 in the blink of an eye! Since summer has hit, his father has decided to let him try a “no bedtime” trial. However, regardless of how late he stays up he’s back awake around 6:00-6:30! Thank you to all who posted advice. I’ll be making adjustments starting tomorrow as he’s already asleep for the night.
