You will pry my AZO tablets from my cold dead hand! I dont take them all the time, but once in a while, maybe 2 days a week, i need a dose. Mostly i drink plain water, tea, herbal tea, or once a week a crystal light. Hmm, could be the crystal light irritating me? I dont use ice tho - just room temp Perrier or Fuji water. The apartment water stinks of bleach and turns my stomach, i cant drink it unflavored.
