Good afternoon all respected doctors. My age 37 years, weight 50 kg, height 5 feet 5 inch. I have insomnia problems from last 10 years. I am taking mirtazapine 3.5 mg/ clonazepam 0.5 mg (any one from above). Many times I had tried to sleep without medicines but not slept properly. Awake 4-5 times. During day I feel tired/anxious/exhausted. I tried yoga/ pranayam/walking / take milk at night but no improvement in my sleep. During night my mind wondering unnecessarily. However I sleep properly with taken above medicines. I want to know following: - which tablet (mirtazapine/clonazepam) is better and have lower side effects. - will I face any serious problems with these medicines in future if I continue them whole life. - should I need any checkup/tested annually if I take above medicines. Thanks for your valuable advice.
