Hey everyone, sorry for not responding sooner.

To Mark, I'm not sure about the restlessness. Very rarely, I get restless some nights, but I haven't taken the time to notice if there is correlation between that and my grogginess. I will pay attention to see.

I usually have no problem with my energy supplement most days. For example, today I took it and feel perfectly normal.

I guess everybody just has those days where they're tired out and they seem to drag on forever. But, fortunately for me, this doesn't happen very often. On average, it's usually an average of about one day a month.
