The fact you have paid and you are two days away shows how serious you are about it.
You will be fantastic you’ll have on average 4-10 days of discomfort and then have years of glorious boobage to make up for it I’m just about 12 days post-op I wrote on Facebook last Saturday morning after my Xmas party that no longer did I feel like the ugly duckling stuck on the corner I felt bloody awesome. It’s stupid they are just boobs, that’s all, but after wanting them soooo long it’s really great. Start getting excited 😉
