I've been taking 1800 mg 3 times a day for a few weeks. This stuff makes me higher than a kite. Light headed, dizzy, brain fog, short term memory loss. I've gained 8 pounds. I take it for neurogenic pain and so far it hasn't done much for me except make me feel loopy. My heart races if I stand up fast, and I can feel it pounding in my head and hands. I'm gonna hang in there and see if it is worth all of this is the end. After reading everything posted here I am rather freaked out now about this drug. I took my two caps 2 hours early trying to get back in a schedule I can hang with and I thought I was gonna die for about an hour. I felt like my head was going to explode and I was gonna have a heart attack or a stroke...I'll never do that again.
