Was taking Sudafed for about 5 days for a nasel infection, along with Nasonex, and Calrenex. Though in retrospect, this was probably too much medication. But the day after I started taking this, I immedietly began to get feelings of anxiety, worry, fear, nausea, headache and dizziness. After 5 days of this hell, I stopped taking all medications, and probably never take Sudafed again. It has been about 2 days since I stopped taking the meds. and I am still recovering from their harmful effects. I dont know which is worse, having the nasel infection or dealing with the side effects of the drugs. I still have nausea, and slight head pressure.
