So my friend stole some of my primatene. Last time at wallgreens I got 2 60 table boxes. Wich lasted 30days at 25 mg 2x per day. But this time I bought just one from wallmart and my friend took half of it and I'm allmost out. I can probably buy an other but then will I have to stop or can I buy more? How many can ya buy a month? Since I bought at wallmart will they know about it in wallgreens? Or is it just keep track per store?
