I took 2 Hydrocodone-APAP 7.5-500 and 2 Tylenol Cold Head Congestion SEVERE, and 1 claitin. I feel weird now.?

You obviously had a concoction of gesic drugs and you should know that taking these tablets in a gap of two hours is not wise. The best medicine to clear a congested nose is a small cup of warm water with a tea spoon full of table salt dissolved in it and you should put some drips in your nostril before you retire to bed.
