I had drifted off to sleep in the recliner while watching football on tv with my husband. I kept partially waking up with the horrible feeling that I was about to die or pass out. Its hard to explain but really, really frightening . My pulse was normal but I had a terrible feeling of doom which is still with me, now about 45 minutes later. Feel nauseous and legs sort of pulsing. Really feel something awful is still about to happen i.e. I, dying. I,m not exaggerating,i,m so scared and don't know what to do.
