Does TMS work?

I have OCD, bipolar 2, MDD, PTSD, and general anxiety. Im on a very good medication combination, along with intensive therapy that keeps me at a good baseline. Keep in mind I'm on the max dose of my antidepressant. Im currently having a breakthrough depressive episode for about the past 7 weeks. I meet with my psych again in 6 weeks, but he had mentioned TMS as an option if my condition worsens or doesnt wrap up on its own. My regimen would be 5 days a week at 20 minutes, for 7 weeks. Anyone have any success stories? Side effects? Just looking to gather personal stories after researching online.
