Hi,
How are you? If your medication is not working, it is best that you inform your doctor for proper management. Your medical history is essential in properly evaluating the underlying cause. Long term insomnia is usually associated with psychological or medical conditions. Treatment will depend on the cause.
Take care and do keep us posted.
What kind of insomnia do you have? Did you go to a sleep clinic to diagnose it? It's crucial to understand the cause!! Do you wake up too early or too often? or you go to bed late? Plus: don't forget that caffeine (and teine too) can stay in your body for two days and bother your sleep. And sugar can give you bad awakenings.
Tell us more so we can help!
