Hands down the only sleeping supplement that works for me.
Have 4 tablets of magnesium and 2 of these and I wake up feeling new again.
Turns a 6 hour sleep into an 8 hour sleep.
Not addictive and helps anxiety/improves sleep quality (at least in my experience).
$19 at woolies
$21 at chemist warehouse
Got it a few weeks ago when it was on the same promotion. This thing doesn't work, but in the morning may give feeling of stupidity in your head. And it smells horrible.
