Hello, I am new here. I have suffered FMS for quite some time now. I have read that there is a link between low serotonin levels and FMS. I recently have had mine checked and it was very low <50. I was on Effexor (SSNI)at the time. I wasn't surprised that my serotonin was low because I feel anxious and depressed alot. I have tried many things to boost my serotonin but can't seem to do it. Does anyone know what could be going on with me? or what has helped for them with their serotonin and depression besides an SSRI or SSNI? Thanks so much.
