Bedtime routine for 11 year olds

[fml666]

Please can you share your bedtime routines for your 11 year olds? I haven't really had a routine for DS for the last few times, but he's recently been diagnosed with ADHD and struggling to get to sleep and I think a predictable routine every night would benefit him. He looks constantly exhausted with massive shadows under his eyes. Current bedtime is generally between 9 pm and 9.30pm.

DS 10 is also struggling since the clock change.

Dinner
Lego/drawing/Playmobil/listening to music
Supper around 7.30
Reading
Bed for 8
Light out 9
Falls asleep or has nightmares/can't get to sleep

It's quite difficult. Have had to put bed back to much earlier as he was staying up later and just couldn't get to sleep, I think he was overtired. I find it really hit and miss as to how bedtimes go. And he seems to play up if his Dad is out whereas if I'm out (each out one night a week at a class) he's totally fine for his Dad.
