the only thing that stopped my coughing was when i quit smoking almost 3 yrs ago

I'm in NW Illinois and have had trouble with Walgreens having my meds on hand as well, you would think if they have someone with a scipt they would keep it on hand but they don't (not sure why). If your insurance has a plan to get your meds by mail (three month supply) you could go that way. and being in the Chicago area there are a lot on online options for you. Good luck!!!
