It could be stuck. We talked about this last week in my support group. Have you tried (this sounds silly) walking around and raising your hands in the air? we all had a laugh about it but more than one person said it works. Just raise your hands like you are reaching for the ceiling, or stretching and that sometimes helps. For me when I get stuck a walk usually does the trick. I was in a restuarant and got a piece of chicken stuck and I had to get up and walk the hallway and it worked. Once you get unstuck, tomorrow rest your band and stick with liquids. Have you tried something warm or hot too? That might "soften" the peanut butter too. Wishing you the best!
