I'm not taking the low dose lithium yet as I want to clarify what it is for which is why I posed this question in the forum and will not take it until I understand it. I plan on asking him what it is for at our next appointment but was wondering if anyone knew anything about it.

And yes, he is a psychiatrist. And yes, I see a therapist twice a week. I have treatment resistant depression. I have tried almost every combination of drugs it seems, none seeming to be effective, as well as ECT which worked but only when I was receiving the treatment, not lasting when I stopped. I'm considering VNS (vagus nerve stimulation) as a last resort if the present drug combinations are not effective.
