Linda,
Way to go, you sound like you are doing fine, especially your attitude. (Although it used to bug me when people who had never been through anything like this would say: "keep a good attitude, it really helps"). Getting a PEG is a very simple procedure and nothing to fear.
It just so happens that I finished my treatments right before labor day 4 years ago, so I indentify with you finishing up this hot time of year. Soon you will be through.
Take care,
Danny G.
