Bill - glad to see we've all wondered to the same place. Yes, I'm trying to decide if or how much more to get - "while the getting's good."
If it will stop most viruses - esp Covid-related - it's worth having some around! I've said it before, but sooner or later the virus is going to come up with a solid NASTY form of Covid. It's like an infinite number of monkeys playing on an infinite number of slot machines - sooner or later one is going to hit the Worst-Form-Of-Covid jackpot. Want to have some to help out extended family as well. But maybe a little nose count is in order here... (hmmmmm).
If it is successful with some or all of the manifestations of PASC - that's even better. Then it's something I'd consider taking daily!!
