      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: The block randomization method was used in 3 blocks of 20 people, using the free statistical software available on the Randomization.org website without using stratified randomization to create a random sequence. Then, each obtained number was assigned a unique arbitrary code, including capital letters and numbers, using the Random.org website for concealment. The statistician delivers these codes to the pharmacist to prepare medicine packages, and the coding of identical packages is done with them, Blinding description: All participants use the same medicine packages, the contents of which are the same in terms of color, size, smell, and shape.
Principal investigators are unaware of the coding performed by the statistician.
Doctors, interviewers, and data collection officials are only aware of the code assigned to the patients and do not know to which study group the patient belongs.
The study codes will remain with the project statistician until the end of the study. The statistician will decode them during the statistical analysis at the end of the study.</study_design>

      <i_freetext>Intervention 1: Intervention group: In both groups of patients, propranolol 20 mg twice a day is used as a standard anti-migraine treatment. In the Intervention group, 3 mg melatonin tablets (Razak company) are given. The prescription is to take medicine one hour before going to bed. The intervention will continue for two months, and the study data will be collected before the intervention, in the first month, the second month, the third month, and the fourth month after the intervention. Intervention 2: Control group: In both groups of patients, propranolol 20 mg twice a day is used as a standard anti-migraine treatment. In the control group, the same placebo in terms of shape, color, smell, size and taste prepared at the Faculty of Pharmacy of Jundishapur University of Ahvaz is given. The prescription is to take the medicine one hour before going to bed. The intervention will continue for 2 months and the study data will be collected before the intervention, the first month, the second month, the third month and the fourth month after the intervention.</i_freetext>
