you may find that you do have water retention using Creatine
i certainly did and you'll probably also find that you have a little indigestion and wind!!!
I certainly did when i used it as a supplement my training.
After 14 years of training i wouldn't deny that Creatine works, but i would suggest that natural training and a healthy diet you will find that your strength gain will be similar to someone who supplements.
he only real difference that i believe you will see with Creatine is recovery time gains
