Has anyone noticed a stimulant type response within an hour of taking the new AMPLIFIED version of the Wheybolic Extreme 60?

I previously took the regular Wheybolic Extreme 60 as well as various types of other protein and/or creatine mixes in the past. I just bought the newer amped version and have taken it twice, right after workouts. . then eat, shower and go to bed. I've noticed both times laying in bed an odd feeling in my stomach and have felt like I took a hydroxicut or a caffeine pill, and am restless with a hard time sleeping.

The old version never did this, nor has any other. I have taken hydroxicut and/or caffeine before but never within less than 6 hours before bed for obvious reasons, point being those factors are ruled out. Am I alone on this? What about other side effects?
