My son has been using one for a decade and doesn't mention it anymore.

If it's a major distraction and you're overweight, you could try losing some weight. That would make the soft palate less flabby. Also there are surgical procedures, not necessarily with a knife, that can reduce it's size.

The potential liver problem is more worrisome. That needs follow up. Good luck!

I've got to get a physical! Ignorance *is* bliss.
