Yes, you did: With the Sudafed! You didn't mention which formulation you used, even if it was the lowest concentration, you shouldn't take more than twice a day. Don't take anymore today, check your blood pressure, drink lots of fluids, orange juice, and vitamin C to acidify your urine and get rid of Sudafed, see your doctor if any problem
