Right at this moment, I have a green tongue. I stained it while trying to dry swallow an antibiotic capsule (without the aid of drinking) for the past 2 minutes. In the end, I had to go drink water to wash the capsule down. I don't get it. I've managed to dry swallow the capsules previously, and both times I was stuck in the middle of performances where water wasn't available. Then, in order not to miss the timing for consuming medication, I just popped the capsule in and swallowed without much thought. Now that water is just within reach, I can't make myself repeat the trick again.
