I'm so happy to hear you've been able to reduce your headaches by reducing your medications.
I wonder as well whether or not my long list of medications are causing my headaches. Sometimes I feel worse on the medications than I did without them.
I too have to be careful of Serotonin Syndrome. I usually can feel it coming on, my triptan stops working and I start feeling really weird, out of sorts.
I wish you all the best getting healthy. One day when I have the energy, I want to do this as well.
