yup, been using Zstack for months. (not vaxd)
caught a cold a week ago, and stayed home from the office (more to allay the fears of co-workers, who all have been vaxxed but who all would have FREAKED out if they were "exposed" to anything resembling the sniffles).
Long story short:
night 1: cold/shivers. minimal sniffles, a mild headache, sneezes, sore throat from drainage. Tired.
next day: weak, tired, pretty comfortable otherwise. Slight headache, pronounced head stuffiness.
full day 2: outside for fresh air, raking leaves, still a little head stuffiness. Blew my nose once or twice.
back to the office on day 3.
Could have been flu, but I wouldn't know, since I did not get a test. Also, I am exposed to the vxd every day, so those tcells are def an issue.
It was a nice break from the office anyway. My annual cold/flu was minimal, and never developed into the standard laryngitis that I get almost EVERY time.
The zstack and the rest really did the trick - for me.
