I had an NG before inserting a PEG tube my first and second fight (Ten years ago). I remember the NG not so much hurting (In my mind at the time I was saying that it burned, etc.), but I believe in hindsight it was just something new to me and took an adjustment period. As far as your question we can all walk the same path but our footsteps land differently, if that makes sense. It is really strange how these miracles we call bodies act and react so much differently to the same treatments but that's just how we are built. I quit thinking about that and focus now on how I can best adapt to work with my body instead of against it. Sounds like your husband gets that which is a win! Prayers and all my best!
