About 4 weeks ago i started taking zma every night. And about 2 weeks into doing that i started noticing a couple of things that I'm wondering if anyone else has had happen to them. I started needing less sleep, i wake up after about 6 or 7 hours, and i feel rested, not tired or anything. i have more energy throughout the day. This is the only thing I've changed, that i can think of. Haven't changed diet or training, work got alot busier which has keep me out of the gym 2 to 3 days a week, leaving me with only 4 days training, other than that, nothing really different. Anyone else have any zma experiences like this, or is this just something unrelated?
