Attached is the long version of how treatment went for me. Short version: reducing stimuli, various meds (I think venlafaxine was the most helpful for me)—though I have now weaned off all meds except for scalp Botox, lifestyle things to manage symptoms and avoid triggers (lack of adequate sleep is my foremost trigger). My symptoms have gone up and down a little since I wrote that post so I’ve adjusted things a bit and try to be flexible. This is a chronic condition that will ebb and flow a little over time, even when symptoms are generally well managed.
Patience is a must, though—it took several years to get symptoms to a manageable level. But it did happen and happens for most people with a decent treatment plan. Good luck
