For this purpose, we prepare four sheets of paper. On two sheets of paper we write the letters I meaning "Intervention" and on two sheets the letter P meaning "Placebo". We mix the sheets together and put them in the desk drawer. Upon the visit of each eligible patient, one of the sheets will be drawn randomly and based on whether the drawn sheet is I or P, they will be assigned to one of the two intervention or control groups. It should be noted that the drawn cards will not be returned to the table drawer until all four cards have been drawn. After randomly pulling out all four sheets, all the sheets will be returned to the drawer and the above procedure will be continued for the next four patients until the desired sample size (80 patients) is reached, Blinding description: The drug and placebo will be prepared in similar containers by the respected pharmacist, and the smell of rose water and the combination of the taste of sugar and grape vinegar in both groups will prevent the blinding process from being disturbed. In this study, participants, researchers, clinical caregivers, outcome assessors and data analysts, as well as the safety and data monitoring committee, do not know which container is the drug and which is the placebo. 3 Chronic Fatigue Syndrome.
