Anyone had implant replacement?

Hi all,
I'm scheduled to have my expandable implant replaced with a standard one in 10 days. I'm excited and hoping it will be easier than the reconstruction surgery. They tell me it's like "changing a tyre"!
Has anyone else had something similar? What was the recovery times like? I've done the lymph removal, nerve issues, reconstruction, so none of these are a factor.... I've been offered a lovely new job to start the following week and am hoping for a new start, clean slate, no cancer story!
Thanks
