I've got something similar. I have a tremendous immune system (been sick only 2 times since 1992 - both were wicked common colds) now i have the slight twinge of a soar throat, but whenever I lay down to sleep every night - i have a horrible cough that won't let up - but it only occurs when i'm laying down - not in the day. in the day - i can feel a slight irritation in the throat. This worries me b/c i rarely get sick b/c my body fights off germs very well - always has because I treat it like a temple. 128 oz of water 1 centrum multivitamin 1 vitamin c pill (1000mg of C) 2 calcium capsules 2 fish oil capsules 1 amino acid capsule Daily. Now this damn cough comes and and screws with my body and mind.
