This is an excellent observation. I too get the same thing if I do too much stims and spike my BP too high. It's almost like drinking myself sober.
I wonder if you are experiencing the same thing??
I have a fine line where if I do way too much, it almost makes me want to take a nap. Odd as it sounds, it sounds to me very similar.
I love Blue, but too much def spikes my BP. I also crash if I take too much. I am finding that 2 scoops with a large glass of water in the morning is perfect. It does have PEA in it, and that is possibly the culprit. I can always adjust the formula and send you a sample portion of it with less PEA and stims..would you like to try that?
**edit** The flavoring is being changed next week as is, so I can send you a sample and lower the PEA on all of them maybe? or just yours.
