DS1 (Y13) has long-term sleep difficulties. It takes him about two hours to get to sleep and then he wakes 2-3 times a night and has difficulty getting back to sleep again. He has cut out caffeine, switches screens off an hour before bed, etc. He is permanently exhausted and not capable of much before about 10am.
During his GCSEs he was prescribed melatonin by CAMHS.
As his A-levels are approaching, he made an appointment with the GP, who has prescribed a low dose of zopiclone (not to take every night, just for the nights before exams). Luckily all but one of his exams are afternoon papers.
