Hi, Akhira ... I didn't have any psychological issues with artifical devices on my body, since I've worn glasses since first grade, had fillings and crowns in my mouth for decades, and my husband wears hearing aids. I now use a walker/wheelchair as needed also.
Like Barry, I feel the PEG has been a life-saver. I got mine in January, and it's quite a convenience as well as life sustaining. I've taken my syringe and boxes of supplement to the hospital when my husband has been in, and can duck into a restroom or pull the curtain for a quick meal and back to his bedside in 5 minutes.
As far as artificial supplements, that's an individual choice. If you are a PALS caring for yourself for meals, and can do the shopping, chopping, cooking, storing, etc. yourself, or get someone to do it for you, that's great. I don't have the energy or the interest in calculating calories and nutrients to make sure I get everything I need. It's really convenient to have it all ready and measured in packages and just not have to worry about it.
But people vary in the amount of work they are willing or able to do. If anybody wants to "go natural," I say more power to them!
