So much for the fun little head cold I have.  It was wonderful the first 2 days because my sinuses were so filled that I couldn't feel my topotecan headache.  Now my cold has developed into a full blown chest cold.  I have a constant chemo headache, horrible deep whopping cough, and lost my taste buds.   Great.  So I have chemo side effects AND cold symptoms!! Bet the makers of Robintussin haven't come up with that combo.
