I did the same thing. I work in the medical field so knew this was coming. My Albuterol inhaler is the only way I can do things outdoors certain times of the year. My sympathetic primary care MD wrote for a stockpile several months ago.
I was "pre-warned" the hard way. Doc said they will outlaw the present delivery system so I may as well get used to the new one. The albuterol is supposed to be the same.
