They lean you back, put an IV in (the IV actually doesnt even hurt because theyll already have the gas on), tell you to count down from 10; I dont think I even made it 7.
Next thing I know, Im in the car asking what time it is every few minutes.
The most important thing is taking care of yourself afterwards. Gotta change out gauze pads every few hours until you can get the bleeding to stop. Take Advil by the sh*t-tons for several days. You arent going to be eating solid food either for awhile. But the doctor will give you a sheet of paper with instructions and stuff afterwards.
