Slow progress

I'm on the home strait of the Diagonal Matrix, but boy is it slow going. It's a 1x1 rib that runs around the back of the neck, down the front, around the small of the back and back up to the neck. It takes about 40 mins to do one round. But I am getting there, gradually. Did 5 rows (of 25) yesterday. Oh and it increases by 4 stitches on every other row which is not helping!
