Let's say you go to bed at 11pm...
Have your shake at 10:15pm or so...slug it down and flip through channels, watch Leno or something take that one last right before bed-time piss then go back into the kitchen and take 30mg of zinc w/ magnesium at 250mg and 10-20mg b-6.
Or do the same and just take a ZMA formula instead of plain zinc alone. Drink it down w/ 8oz of water...if you wake up tp pee in the middle of th enight like I always have to...have another shake ready for you in the fridge. Hope this helps...
