Why do you feel you need one?
Coffee.
Yeah I've hard 3 weeks to a month. Realize that even when you're not fully saturated, you are benefiting from the creatine just not to the same extent as if you were fully saturated.how long does it take your body to actually get saturated with creatine? is it really a month on 5g a day?
In all seriousness, go for it. It's proven to be safe and effective, and it's cheap. If you want to read more on the benefits of it with evidence from scientific studies, not anecdotes, see the following: http://examine.com/supplements/Creatine/.
What? Yes creatine does increase water retention in muscles, but it also leads to increases in power inputs resulting in strength gains. Gains aren't measured purely in increased size of muscles or increased weight. And while you will lose some water weight from your muscles if you cycle off, this happens during a normal cut and at other times.
You also don't need to necessarily fast a full 16 hours. 12-14 hours still has benefits and may fit your schedule better.
Saturation is a chemistry concept. If I remember correctly, saturation is when substance A is dissolved in another substance to a point where additional amounts of substance A wouldn't dissolve. I'm sure Wikipedia can explain it better. No not a sign that you should stop taking it. You need to continue to provide your body with it to maintain saturation. Though some people do say that you should cycle on and off creatine for tolerance reasons - not sure the validity of that.
