Notice you have one group of big pharma shills that say

"Hey, take as much as you want, there's no possible detrimental repercussions that might occur."

And then another group who have actually taken the nonsense, who are almost unanimously stating

"Hey, this guy is right, I was on this shit for a month, and I've never been the same since"

Insomnia is the first sign that the physical dependence has taken over your physiological functions, and don't EVER expect to get to sleep again without some extremely powerful secondary agent, like the anti-psychotic Olanzapine, which will knock you out for 12 hours straight.

I don't suggest Olanzapine, or any Anti-Psychotic though, and specifically not that one, as it will make you gain 200 hundred pounds in 6 months, with no way to lose the weight again.
