'Sloshing' Since the Day of my Surgery Last Week. How Soon Does That Go Away?

I had 250cc high profile Mentor silicone gel implants placed submuscular less than a week ago. Since the day of surgery, I've had sloshing noises from both breasts. My doctor saw me yesterday and said that there is nothing to worry about and that it is not dangerous. I'm just concerned that the sounds will remain long term. Typically, how long until the noises go away? I'm a little embarrassed to move my arms around my fiancé.
