Hello ,
Thanks for using healthcaremagic.
Insomnia (sleep disturbance)are of two types.
primary insomnia is without any reason and only problem of sleep disturbance is there.
Secondary insomnia is due to some physical or psychological problem in which specific treatment of that problem is necessary.
In both types benzodiazepines group of medicines can be useful with doctor's advice.
Some measures called "Sleep Hygiene" is useful, which you can search on internet.
In your case I think primary insomnia and it is worsened due to not having treatment taken since long.For exact cause your examination and
hormonal check up needed which can be done by consulting doctor/
psychiatrist.
I suggest start drinking a cup of warm milk before 15 minutes going to bed.Also do regular exercises.Avoid spending time in your bed except sleep.
If still problem not resolve in a week, with above information keeping in mind consult your doctor and find the solution.
Hope I have answered your query.late me know if still any info needed.
