I have an 11 hfa ds, diagnosed and started melatonin in July,
I’ve been monitoring his sleep with a Fitbit watch. It shows that his claims of frequent waking in the night are totally true,
We have 2mg Circadin, a slow release melatonin. Since starting, ds will sleep within 5 mins of lights out, instead of45-90 mins. He sleeeps, generally, ok till the early hours, then has lots of wakings again,
The doc told me I should phase themelatonin in, starting 15mins before his usual sleep time 10pm, then taking it back in daily increments of 15mins till his bedtime was where we wanted it to be. This worked brilliantly.
However recently, he had a day where he was tired out after tea at 6pm. I sent him to bed - did the entire routine, Including melatonin, but just an hour early. He was in bed, lights out by 745 Latest. He didn’t get to sleep till 9pm!
So, this waffle was intended to say I think melatonin helps as part of a routine. If you want to change sleeping times, do it In 15min steps, not a whole hour at a time.
