I had mine put in under a local, it was a really funny experience. They took 30 mins to find a vein that worked, so I am sure there were some quite annoyed people. so I kinda drifted in and out and then woke up to them discussing me, apparently I had a major vein in the way, and the doctor was a little hesitant to go ahead, I think he hadn't put this type in before. So I was really impressed he got another doctor to help him with the procedure. It was really funny listening to them working out the best way to do it. At this point I don't think they knew I was awake lol. I felt I was a star on Hospital TV, a pity they noticed and sent me back to sleep. I have to keep it until the end of the year. Just make sure you ask them to be gentle when they access it, I was sore for a week after one treatment.
