      <i_freetext>Intervention 1: Intervention group 1: Patients in the first group will be treated with 37.5 mg of venlafaxine daily with 100 to 500 mg of gabapentin daily. This treatment will continue for patients for 12 months. All questionnaires will be completed by patients before the intervention and once every three months for a year (12 months after treatment). Intervention 2: Intervention group 2: Patients in the second group will be treated with 37.5 mg of venlafaxine daily and pregabalin 50 to 300 mg daily. This treatment will continue for patients for 12 months. At the beginning of the intervention, as well as once every three months for a year, all questionnaires for patients will be completed and compared with the other group.</i_freetext>
