How do you find the right "medical professional"? I spoke to a psychiatric doctor about this recently, and he literally laughed in my face and said its all bogus.
Find providers who don’t seem too eager to give you as many treatments as possible. I’m getting ketamine infusions for pain through a pain specialist but he also treats depressed patients. A pain specialist may be able to help you as much as someone focused on psychiatry as they still know the drug well and often know how to treat depression
