Feeling odd

F

lightheaded and woozy on the recommended amount of 2tbs of over the counter cough syrup, this is what I presume a medication high feels like, ear infection and cold aren't helping me out at all. My stomach is also a bit weird from the meds and my heart rate was at 90, about 20-40 bpms above my average resting heart rate, please help. I hate this.
