Feeling sick-ish, I went to a "drip bar" for an immunity boost. Here's what happened.

THE NEXT DAY
After a restorative sleep, I immediately realized upon awakening that whatever sickness I was on the verge of didn’t bother me as much. I’m not a morning person, but I didn’t have to drag myself out of bed like I usually do and felt a subtle boost of energy throughout the day. Also, I was better able to focus during work and was more productive than usual.

DAY TWO
My energy levels were stronger and more even throughout the day — still no 4 pm caffeine crash. My ability to focus was still slightly enhanced and though that feeling of fighting something sinus-y returned a little, it never really materialized into a cold.
