I am one of those that can't sleep at all on ZMA. I ended up taking all my ZMA in the morning for fear of sleeplessness.
I don't trust myself with a sleep window, there's too much potential from the noisy neighbors.
I might try the taurine trick, though slowly with the ZMA. I only do my Mg in the A.M. now, after that bad ZMA nights.
Anyone know what ZMA (mg?) keeps one up so bad?
