I was taking the GNC ZMA but then I switched to the Biotest ZMA. After that week of adjustment I haven't had any more problems with restlessness and midnight waking (at least ZMA related, 2 year old related is a whole other story).
"And for crying out loud. Don't go into the pain cave. I can't stress this enough. Your Totem Animal won't be in there to help you. You'll be on your own. The Pain Cave is for cowards.
