I live about 45 minutes away from where I had surgery, and the drive home was a little unpleasant, but that's mainly because my dad drove and he's a bit of a scary driver. The drains have the potential to be messy if you're not careful, but my dad and I were able to empty them while I was sitting up in bed and we didn't spill a drop. I don't have any Garramone-specific advice since I went with Steinwald, but I can link you to some general advice and checklists once I get back to my computer.
