Leave a small plastic tub/box/food container in the cage filled with moist sphagnum moss, leave the lid off or cut off one corner of the lid so the snake can easily enter/exit. The snake will probably spend alot of time in there.

Place about 1/2 the moss tub over the heat. Re-moisten as needed.

Some people try a warm wet cloth to rub the eyecaps. This is only OK if the eyecaps are already softened by high humidity.

Sounds like the snake is dehydrated. Are you keeping it in a glass tank/screen top? Sometimes irritants cause repeat sheds. What substrate are you using?
