Started on ZMA 3 weeks ago. I've noticed that I'm more alert during the day. Unfortunately, I've also gotten more alert during the evening. Have been on 'sleep assistance' meds and now with ZMA they don't work any longer. I've switched three times on sleeping pills and none of them take the edge off the ZMA (2 pills at bedtime). Any suggestions - it gets lonely in the middle of the night listening to the cats bowling each other down the hallway.
