      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: Eligible patients will enter one of the two rows of the trial in a one-to-one ratio (1: 1). Allocation will be done by permuted block randomization method. The size of 4 blocks will be selected. The allocation in each block will be simple randomization. Randomization will be done centrally and before the start of the study by a person who has no direct role in the entry of participants with a random number table. People who include patients in the study will not know the order of assignment. The order of allocation will be hidden from the researchers by thick, tightly packed dark envelopes.
The medicine is given to patients by researchers. The drugs and placebo are provided to the researchers in the form of packages containing the study drug and the placebo for one month. The drugs are provided to researchers in packages of the same shape and only after determining the order of treatment. There is an expiration date on the package. If the expiration date of the package is less than 5 months at the time of entry into the study, the package will be returned to the allocation officer and the package with the appropriate expiration date will be given to the researcher in the same way. In the event of a serious adverse event for the participant, unblinding will be performed immediately for both the participant and the researcher. In the event of a severe adverse event in more than 12.5% ​​of participants (at least 7), unblinding will be performed for the researcher for all participants, and if the adverse event is due to melatonin use and is unexpected for melatonin, It will be done for all participants as well, Blinding description: The study will be double-blind which means the patients and researchers who include patients in the study will not know the order of assignment. The order of allocation will be hidden from the researchers by thick, tightly packed dark envelopes.</study_design>
