symbicort
It’s an inhaler corticosteroid and anti inflammatory often used for asthma but incredible for post infection cough.
If I’m ever sick and have a cough, this puts a stop to that symptom and recovery is so much faster. Don’t even touch any over the counter cough medicine over this imo.
Omega mart in Las Vegas might come close?
Can’t think of large scale ones unless you include the rest of Las Vegas.
