It seems like, if I wait long enough in the evening to take ZMA on empty stomach after dinner, I either fall asleep, or I forget.
So, would there be any problem with taking ZMA in the morning? The stomach is definitely empty then. I don't care about whatever effects ZMA might have on my sleep, I'm not taking it for that.
Any potential interference with TRIBEX if taken at the same time? (unlikely, but better safe than sorry)
