Bloop,
I had a PEG and had it placed on the advice of my Dr. Looking back I think I could have gone through everything but the surgery without it.
It was a painful process and even more painful when in the hospital recovering from surgery the nurses pulled my PEG out on accident and had to have it surgically replaced...without pain medications or even a sedative.
On a fun note with a PEG you can still consume alcohol...with the added benefit of "cleaning" the tube

If you have to have it there's no reason you can't make it fun, just don't mix with pain meds.
