Vitamin c for depression

two years ago I discovered the world of orthomolecular medicine and did my first trial run of vitamins for depression and fatigue. My health took such a spiral coming off antidepressants due to serotonin syndrome that I didn't follow through. Today I am 6 months off all psychotropic medications and still dealing with some nasty depression ontop of this P.O.T.S. disease and unwilling to try drugs due to what I've already been through. I'm giving the vitamin c another round. I started a few days ago with 100mg and have worked my way up to 750mg as of today. 

I will report my findings. So far I've noticed a bit of improvement but we will see how things progress over the next couple weeks.
