I had similar problems - terrible nausea and headaches, when I first got progressives. I gave up and had new glasses made and stuck these in a case in the dresser. The following year, my ophthalmologist told me to give them a try again after a year of using regular bifocals and no problems. That said, I don't need them for reading - I just take my glasses off. I needed the bifocals for such things as sewing where you can't move the object that you need to see.
