I'm in the same boat as the GP. Talked to a few AMEs about my options back in 2019. SI involves thousands of dollars per year and and only applies to a few relatively old SSRI drugs. Ideally they want you to discontinue your psychiatric drug treatment – great job, FAA.

There's also the BasicMed rules. You can fly with BasicMed instead of 3rd class, but you need to have had a 3rd class to get the BasicMed, so I suggested to the AME that I could drop the drugs for 2 months, get the 3rd class, and then immediately apply for the BasicMed and hop back on whatever I was taking in the first place. One guy refused to talk to me after that.
