Well....many antidepressants have been sister medications for migraine and Ch. You did not specify the medication/antidepressants scripted but most are not effective for CH. Your doc should have first and foremost scripted oxygen as an abortive then maybe verapamil.. which currently is the so called gold standard of treatments not that it means much in the way of CH. The D3 regimen should be looked into as it has helped many more than verapamil..
