Go to the main Forum page and use your Brower's FIND feature. Search the page for the word 'wallpaper'. You'll find a plethora of posts on this subject. I guarantee you'll find ones just like yours. (Bathroom wallpaper removal where parts of the drywall is coming off.) I've replied to many of them so I'm gonna spare myself the repetition.
If you find the posts aren't of use, do tell what you DO find useful, and ask about the 'missing' info. My best to ya and hope this helps.
