it could be, how much did you take?? what did you take it for..
i drank down half a bottle..about 75 ml...
I feel really good, but my heart is racing.
yeah that is not good.. the other ingredients in that can really harm you if you take more than recommended. large amounts of pseudophedrine should not be taken in high doses.
If it gets worse, go to the ER... have somebody drive.
