BLEH. I just chewed two 500mg Vitamin C tablets, thinking they were Cetrinets. Ooohh, that’s sour. That’s reeeaaally sour. I should check those bottles first; I’d forgotten I’d refilled one of these Cetrinets sample bottles with generic Ascorbic Acid. Gah. I need to brush my teeth and get my salivary pH back up. Excuse me.
