Cough and Nasal Congestion
"This medication cleared my completely congested nose in about an hour. I could breathe perfectly clearly through both nostrils! However, as others have mentioned, it made my heart race, and when I was exercising later that night, I felt lightheaded and had to quit early. I also couldn&#039;t sleep that night. My heart was feeling very fluttery and I was wide awake in bed. "
