I've been running my body down the past few weeks, drinking, no sleep... I had a heavy weekend of drinking last weekend and the day after, on Monday, I had a fever for 2 days, and night sweats, and still have a bit of a cough (it's been only about 5 days since the weekend). On Tuesday, it seemed overnight, I developed typical canker sores in my mouth and a larger irregular red shallow patch on my upper gums, which kind of hurts when I eat.
