G'afternoon microdosing
Definitely agree with Chfather that the antidepressant did not trigger a cycle for you.....and, I'm also not convinced that microdosing is an effective treatment for clusters.
As Vipul mentioned above, high flow oxygen therapy and the D3 regimen are your best bet in managing your clusters.
As to Mirtazipine, most, if not all anti depressants in the SSRI class are contraindicated when it comes to busting due to the risk of serotonin syndrome....a quick Google search shows the following:
warnings
Serotonin syndrome warning:Mirtazapine can cause a life-threatening condition called serotonin syndrome. Your risk may be higher if you also take other drugs that have similar effects as mirtazapine. These include antidepressants or triptans, such as sumatriptan and zolmitriptan. Symptoms of serotonin syndrome include agitation, hallucinations (seeing or hearing something that isn’t there), confusion, trouble thinking, coma, coordination problems, and muscle twitching. They also include stiff muscles, racing heartbeat, high or low blood pressure, sweating, fever, nausea, vomiting, and diarrhea. Call your doctor right away if you have these symptoms.
Besides these dangers, the therapeutic effects of busting may well be blocked by the antidepressant.
