This topic is funny as I recently went from Spiro to Cyproterone Acetate myself. I wish I could say I don't pee as often but I'm honestly not sure. I still have to go a fair bit in a day. Maybe just not as back to back as with the spiro. So far I've been enjoying the effects of CPA now that I got through the weird high/low crash. I take an anti-anxiety/depression med as well so that probably staves off the low periods just fine. The body hair loss has is super comforting, while the head hair growth has been quite nice, though I think Spiro was doing well in that regards. I had only switched because the dose of spiro I was on wasn't lowering the testosterone enough, especially given my estrogen levels. I've got my first bloodwork since the switch, so let's see if CPA has done it's job or not.
One thing I will say, especially if you take premarin, is I feel a bit safer with Spiro + Premarin than CPA + Premarin. If my financial situation was better I'd switch over to Estrace and pay for it but I...just don't make that kind of money to comfortably do so. I still might anyway depending on how my results go and of course, a talk with my doctor. Though if I'm talking saving money, I probably should just go straight to injections since they're covered on my drug plan (yet Estrace isn't, Ontario's Drug Benefit plan is so much nonsense sometimes XD)
