Well the results are in.... I did not croak vaping with the flu.
The upside of things is the worst flu symptoms lasted 2 days ie. headache, fever, muscle aches etc.
The thing that amazed me is on day 3 the cough was almost gone and now on day 4 hardly any cough or stuffy nose.
When I used to smoke analogs the cough and stuffy nose would usually persist for a month or so after a cold/flu.
So vape on when sick is the way I see it!
