hiyya
i am the same hun, I am a 34D and looking to go to an E or F cup aswell.
I was told they say its roughly about 150cc for every cup size. So i assume going up 2 cup size would be roughly around 300cc and going up 3 would be roughly 450 cc . Although if you have unders you should go up a size because the muscle restricts the implant. I havent had my consultation yet though just going by what i have heard from others on myaspace so dont know how right that is.
Can i add you as we are both looking for the same answer.
