Its 4.21am Ds5 is still awake his meds (melatonin 40mg) have stopped working again , he has had 2 hours sleep since Sunday and yet is wide awake and full of beans 
I'm taking him to the doctors after school as I make a point of sending him in even with no sleep as he isn't tired etc when he goes in and his teacher doesn't believe me when I tell her .
I'll be lucky to get my Doctor to up his dose or anything else as the dosage was only changed at the end of November .
Dd has suspected As/ADHD and is in a very strict bed time routine .
He just can't sleep and when I ask him why he just says 'It won't stop' or 'my head won't shut up' 
Is their a different medication we could try as this one just keeps stopping working which is a lot of stress for me & especially Ds .
On another note are their any other forms of Melatonin other than tablets as it ridiculously hard to get him to swallow 2 tablets not that he should have to at such a young age
