I absolutely love this, and it works for me. Other meds make me sleepy or make my heart race, this is perfect for me. I need to know where I can purchase this if it is still available. Can you help me? I have terrible sinus headaches and this has been a wonderful medicine for me, now I can't find it locally. The doctor had given me a prescription with refills available, but I can't get it at the pharmacies. Thanks
