1st vial of this new insulin and start having chest pains when I do any thing strenuous. I see low potassium maybe a culprit  wondering if anyone else had the same result. I have been a type 1 since 1980  so I have been well experienced in all kinds of different meds over the decades. any input anyone has on this new generic insulin I would appreciate.
