Amen. I've had the same impact and I've seen the same thing reported on this forum. It's not like somebody slipped me a roofie, I just fall asleep easier and deeper. I now routinely wake up at 5:30 or earlier feelin just fine. If you're having trouble sleeping GABA helped me (100-1000mg in the evening before bed) or melatonin (1-5mg but look at the label, some have calcium or a sturdy dose of b6 which I already have via ZMA) Speaking of ZMA, I've found most formulations to be a good source of magnesium because it's typically aspertate which I've read is a better form than oxide.
This gets asked all the time in regards to ZMA. I've already tuned
out the details but Ca competes with either the Zn or Mg for absorption. (I think it's Ca and Mg compete and Zn in high doses competes with Cu?) Any way the two aproaches I've seen advocated are:
1) give zma 30-45 minutes on either side with no Ca or even any food.
2) say "fuck it" and wash those buggers down with a milkshake and cottage cheese. Maybe they do compete but it's not like it's 100% one and 0 of the other.
I've done both and didn't really notice a difference. I split the difference by just skipping my pre bedtime cottage cheese a couple nights a week. It's not like your body runs out of most vitamins or minerals in 24 hours.
