Take the good when you can and remember this on those bad days. I tried 2 times yesterday and had to get someone to stand in for me which was another 2 tries to get it working. I got it right on the first shot but he was leaking so I had to try another spot and it went down hill from there. I am glad you are doing well and have changed the fluids to something that does not upset your patient. It usually doesn't take them long to figure out it makes them feel better and then it is usually no problem giving it to them.
