Heya! I have 3000cc implants and it took me quite a while to adjust to the girth! I kept running into walls and knocking the shampoo over in the shower, that kind of thing. As far as the pain and stuff, it lasted a few weeks, but after the first week, I was too happy to really care. As far as smaller implants, I don't really know, never had any before. Anyways, I hope that this rambling answers your question, sort of?
