A history of 2 meds at the same time will make your case more difficult, but it's not a "hard no" (an FAA doc described complications like this to me as a "yellow flag"). If you want to apply while taking a single medication, you will first need to establish a track record of being on the same medication AND dosage for six months. You will definitely need the services of a HIMS AME, and most likely an FAA-designated mental health practitioner, but start with the AME. The FAA considers these cases on a case-by-case basis, based on the unique circumstances of the applicant.
Because of your history of taking two meds, the off-medication route will be a bit more complicated as well, and similarly start with a HIMS AME and likely a workup with a specialist.
