I am 37 and have severe COPD with Emphesema. I have ordered several times from GenericDoctor and am VERY HAPPY with thier prices and service. My Primary Doctor approved the Medications. I can get my meds for alot less and do not have to do without. I also can keep an extra supply of antibiotics on hand, because I can not afford to suffer a lung infection. Thank You GenericDoctor you are saving my life.
