Should I add theta TMS onto treatment plan? Is it helpful or risky?

I’m currently doing regular TMS (18hz , 120%). All the technicians keep recommending I add 3 minutes of theta TMS (5hz and 50hz) onto the end of the regular 20 minute session as a boost. They said all the patients being treated right now are doing it and that it’s safe & an added benefit.

I was already so hesitant about regular TMS, and I don’t want to overdo it with my brain. I’m wondering if theta is a common practice/successful or if it’s too new/too risky to do ?

TIA 🫶🏻
