He was coughing up stuff last night, but after he took cough syrup (small steps, right?) he slept the rest of the night. He stopped by the house this morning (a couple hours into his workday) and I loaded him up with hot chai & honey again.
I plan to "garlic" him tonight.
I also found a "recipe" where you cover sliced lemons and ginger with honey, then after it sits a bit, you just put the honey in the bottom of your mug and add hot water. Sounds tasty to me!
