I had to give up spiro - the itching was truly infernal, I'd open cuts sometimes, all the sebum in my skin was dried up. When I started it with it I didn't realize that I needed to hydrate constantly even if I wasn't thirsty and went through an alarming episode where I felt like my blood had turned to jello, I couldn't stand up, etc. Fun stuff. Follow your doc's advice and then some, and you'll probably do fine.
Now I just don't bother with anti-androgens as transdermal estradiol keeps me in the low male/high female range for T anyway. I plan to have an orchi this year, too.
I never craved anything weird, but then I live on a very straightforward diet anyway. I'd just dump some NaCl into a pint glass of water now and then.
