Oh yeah, totally normal. All kinds of crap comes to the surface. You wade through it. And if you don't drink, after a while it won't keep slushing back at you.
As for your sponsor, is this a new one or the same? I'm glad you are going honestly into stepwork, that's awesome. I didn't even know about a worksheet for one. Cool. Step one took me a few tries, unfortunately. I thought I fully understood my powerlessness, but I was really just bummed out about not being able to drink. A couple relapses later, it clicked.
You are doing very well!
