I consume various types of magnesium each evening while keeping to a pretty consistent routine. Additionally I rise very early for aerobic exercise daily and add strength training several times weekly on top of that. Typically around 8 in the evening drowsiness hits me hard.
I'm getting ready to test out one of these compounds soon. A few people claim it makes a big difference while others experience no impact at all. The situation is identical for that other product whose label is a bit off. It seems to me that these kinds of substances succeed with certain folks but fail with everyone else since the causes behind our inability to rest vary widely just as much as all the possible fixes do.
