I have a very weak spot at the back of my throat , in the area of my uvula, that hangy down thing. If a chunk of anything or a pill gets there, it doesn't move. It just sits there. I have to try to hawk it back out.
Last night for a snack, I had a banana with a little peanut butter smeared on it. After swallowing, drinking and brushing my teeth, I could still taste peanut butter in my throat. I looked for it in the mirror but couldn't see it. I think it was up my throat like the pills go sometimes.
