Hope you feel better @Blueberrybook. When I was sick and went to urgent care (had an upper respiratory infection not COVID or the flu) the doc said I could take 1000mg every 6 hours. I was only taking 500mg because that was one pill. Not sure if anyone else does that, but just passing the info along that if it's not long term and you haven't been told by a doctor or pharmacist otherwise 1000mg is ok (and works way better if you have a headache).

He said Mucinex is good stuff too. Didn't try that, but I know you said you got some of that Blueberry the other day. Hopefully it does something.
