You might try posting this on the medication forum since it is a medical treatment.

Years back my pdoc offered it, but I wasn't about to be able to afford the expense nor the time for it. I responded well to unilateral ECT both times I had it, with no significant memory issues, etc. AND insurance fully paid for ECT.

I haven't kept up with how TMS is regarded now, about a decade later, by insurance. I hope whatever you decide, you do feel improvements.
