Had a tough time sleeping last night because of a nasty sinus headache and the neighbors dog barking at apparitions, so tried a Redline Extreme energy drink for the first time. Did like the directions said and only drank 1/2 of the bottle. Results? Nausea, hot flashes, continued sweating for 2-3 hours, irritable, shaky, cramped stomach, and oddly enough a really bad runny nose. It's not a dang energy drink, it's bottled flu symptoms. First time and last time I ever try one of those things.
