I was taking my usual pills today around noon and one is a capsule. The capsule didn't feel right going down and next thing I knew I was unable to breathe. My body was trying to cough it up but couldn't get any air. I was making grunting sounds while grasping my throat and face turning bright red in the bathroom mirror. Somehow someway I was able to get just enough air to begin coughing but each cough blocked it all up again with no air. It then began easier to get the breaths and coughed like hell. Began coughing up yellow stuff that had gone into my lungs from the capsule. Did that heavily the first hour then sporadic rest of the day, lasted about 8 hours. Was alpha lipoic acid for my glucose and help with rebuilding my damaged nerve endings. Later to verify that yellow I opened up a capsule and saw the yellow powder. I was very close to choking to death home alone. Reading about choking tonight it says to remain calm because panic causes the throat muscles to tighten up making it worse. Yeah, well when you can't breathe and face turning red it's kinda hard to remain calm. I'm opening that capsule and sprinkling on applesauce or yogurt from now on. I never did see the empty capsule. Imagine having this in your lungs all day.
