Okay on my second day of using Zenalean and damn. I don't know if this is a result of the ECY stack but upon waking on day 2 I had dropped about 3 lbs of water. This after consuming about 1.5 gallons of water the day before. Today I can feel the body temperature slightly elevated. Interesting that I don't feel jittery which is a good thing. My observation is this stuff works but its strong so adjust accordingly and monitor your reaction to it. I don't think I will need to use it more than 2 or 3 weeks at this rate.
