Save yourself the frustration and just take down the wallpaper. There are a variety of paper strippers on the market you can try. Or a wallpaper steamer might work. Otherwise, thoroughly soak it with hot water (as hot as you can stand, without fear of burning yourself of course). Use a sponge to apply the water. Use a LOT of water. When you think to yourself, "Wow, I used a lot of water," apply more water. Keep the area you are working very wet. You can use a little tool called a Wallpaper Tiger (made by Zinsser) to score up the paper and allow the stripper/water to penetrate to the glue behind. Note though that this will also score up the drywall and it will need to be patched up. Peal the paper away as much as you can and use a putty knife for the rest. Use drywall joint compound the skim smooth any damage to the wall. Sure it's "easier" to just paint over, but now your spending extra money buying more paint, waiting longer for the paint to dry and applying more coats. The cheap and easy comes out expensive. Just take down the wallpaper.
