My regimen stayed the same. I wasn't on Spiro, I was on Androcur and I have stopped taking that. As for changes, pre-surgery when I stopped taking estrogen, I noticed physical changes but no emotional changes. Post surgery, when I started taking hormones at my original dose again, I noticed both emotional and physical changes. Mentally, it was some moodiness and a little depression. Physically, it was a noticeable change in my skin and significant breast development. As for dropping your dosage after surgery, why not ask your doctor if can stay at the same level? I did--all he asked was if I was sure that I could handle it and we left it at that. It really isn't necessary to reduce your dosage unless you're doing mega doses.
