Sleeping after breast augmentation surgery can be difficult due to discomfort and restrictions on sleeping positions. Immediately after surgery, your surgeon may recommend that you sleep on your back to avoid putting pressure on the incision sites and to help minimize swelling and discomfort. It is also recommended that you sleep with your upper body slightly elevated, either with a wedge pillow or by propping yourself up with additional pillows.    Depending on the size and placement of your implants, you may find it uncomfortable to sleep on your stomach or side for several weeks or even months after surgery. Your surgeon may also recommend that you avoid sleeping on your stomach or side for several weeks after surgery to help ensure that your implants settle into the proper position.
