It definitely does. Don't use Apple products, but setting limits or bedtime alarms (on the switch) helps us all out. It cut down on the tantrums about stopping, it gives them the routine they need (we're all on the ADHD spectrum in this house), and I set it up and it's done (I have practically nil executive function).
Is it perfect? No. But it works for us.
Ah ok. I've been getting the pineapple and lemon lime ones and both are a tad sour and I like that.
Edit: the pineapple one is the one with caffeine
