I know when I tried DNP i was absoulutly miserable the entire time.. I was using 200mg every 12 hours. It was mid January, Low 20's every day.. And even at nite I slept with my AC on, my bedroom windows open with a fan in front of each pulling in sub freezing air and I still soaked my sheets with sweat. I constantly felt dehydrated despite how much ice water i downed.. And the carb cravings were ravenous.. I ate literally a couple pounds of fruit every day... But all in all, DAMN this shit rocked, LOL... I dropped about 12 pounds in 10 days..
