Here's an update as I'm 5 days away:
A doctor phoned me a couple of weeks ago and told me the things I needed to do to prep for surgery. I don't think he had much experience with the trans community. He very breezily told me that I needed to come off estrogen for two weeks prior to surgery, because it is a risk factor for blood clots. He has no idea the sheer panic that being told to come off hormones induces. So I haven't complied with this yet. For the last week, I've been tapering down, and I plan to be hormone free from Friday onwards. Its the best I could do - balancing my mental health against the surgical risk.
I'm also supposed to be a non-smoker. I only smoke one a day, but I'm planning on stopping completely from yesterday onwards, at least until post-surgery. The stress has also been making me drink more, so from today on, I'm also going alcohol free. This weekend will just be a case of gritting my teeth and getting through it
