Most people taking creatine just need to drink water. They drink more water using creatine. In reality, the water/hydration is doing the heaviest lift, not the creatine.
I slam a lot of water. I also have a toddler and baby who suck at sleeping (I've done all the things, these kids just suck at sleeping). Since taking creatine I feel so much more energized. I can make it through the day with just 2 coffees (was previously drinking 5 coffees and an energy drink). Maybe it's placebo. Maybe it's not. I don't really care. I feel the benefit and I love it.
At a certain point I was wondering if it was just placebo, stopped taking it for a month or so, and was quickly back to feeling tired after training. Started taking it again, back to feeling energized. It really does work.
