Spravato

I have been taking Spravato for 2 1/2 months and I don’t feel like there’s any difference. I get sick during and after treatment and I want to stop. Has anyone been in this situation? And if so, what can I turn to now? If my insurance covers it, I might try TMS but I had really high hopes for Spravato and now I feel let down. I’ve obviously tried many different oral medications with no result. What other options are out there?
