My doctor doesn't care about my insomnia. Laura, Cheltenham
"You need to go back to your doctor and ask to be referred to a sleep clinic.
"I think you need to get it sorted soon, and you'll soon realise how much it's affecting you."
I was prescribed Temazepam for my insomnia, which made me very ill. Clark, Kettering
"Many doctors will go back for the quick fix tablets, and tell you to come back another day. This wasn't for you.
"But there is other help out there particularly in clinical psychology, something called Cognitive Behavioural Therapy (CBT) that will teach you how to manage your insomnia better and help you perceive your sleep in a different way.
"So go back to your GP and say I need to see a clinical psychologist and get some help."
Sleeping tablets have helped, will I get addicted? Claire, Bristol
"A lot of people will be prescribed sleeping tablets, and they can help some people, but they can be addictive.
"They can also be psychologically addictive - get you thinking -if I don't take them tonight I won't sleep tonight.
"You need a long term strategy on how to get off these tablets. Go back to your GP and ask from some clinical psychological support and non-drug therapies like Cognitive Behavioural Therapy."
I average three hours sleep a night, I tried herbal remedies but they don't work. Melissa, Port Talbot
