Long Term Usage - Your Guys Experience

Long story short, I've been doing therapeutic ketamine (IM) for a couple years now. It's the only thing that has actually noticably improved my depression symptoms.

I'm trying to figure out the long-term plan of this at this point. With my provider, I've been slowly pushing my appointments further and further to try to get into a "maintenance" mode. But, recently, I'm starting to fall back into the pre-treatment depression.

What have been your experiences about doing this long term? Have you been able to go into more maintenance dosages or are you taking it regularly like when you first started?
