I am very petite and getting the PEG definitely hurt me a lot. I cried during and had a lot of discomfort for a few days afterwards.
It all went away though and I got more comfortable with it. One thing that helped me was to wrap a piece of gauze around my stomach and pin the line up with tape- that way it didn't swing around and pull at my clothes. Yes the smell did smell like vomit.. its your gastric juices and that's what it smells like. kind of gross i know!

I'm sorry sorry you are gong through this. The PEG is your friend though and will help you through the rough times when eating is a chore not a pleasure. I know its weird and hard to get used to but it will make you feel soooo much better to get the right hydration and nutrtion. Being well fed and hydrated will really help with the side effects. It will make all the difference.

Hang in there!
