Well, Spiro has been a damn miracle drug for me. The effects have almost all been positive in my case.
I had borderline sodium sensitive high blood pressure, regularly getting readings of 140/90. An extreme low sodium diet, limiting myself to 700 mg/day of sodium and obsessively tracking every swallow with MyFitnessPal on my phone, reduce my blood pressure to 120/80or slightly higher. (Mom died from a stroke related to high blood pressure. Her dad had a heart attack. My dad would have likely had a heart attack or stroke if his liver had survived the drinking.)
I was put on Spiro. I reduced my potassium intake to 2,800 mg/day, mostly by cutting out tomato concentrates, soups, pasta sauce, that sort of thing, bananas, and root veggies.I raised my sodium intake to 1,500 then to 2,300 mg/day, effectively unrestricted. My blood pressure runs 95/60! The doctor is happy with that as long as it doesn't cause any problems, as am I. I don't have to restrict my diet nearly as much, and I even feel better from another side effect of Spiro, being an antiandrogen. That stopped the mental 'noise' I got from testosterone, with some calm periods showing up about 3 weeks in, and the full effect hitting about tow months in.
I very much looked forward to switching to a gender therapist from the initial psych therapist I was seeing, who had very little trans experience or knowledge. He mentioned that gender therapists were available on my first visit when I spilled the story. He mostly made sure I had the tools to deal with the severe depression and anxiety that had first put me on his couch. The gender therapist has been great at guiding me along, and helping me past the obstacles I generated for myself.
