Take it before workouts with a sugar drink. Carbonated sugar drinks, if of a high GI nature, may enhance its uptake in the digestive tract.
No need to load. I take 5 grams. If I had a low amount of animal flesh in my diet, I'd take 10 grams.
It will not make you fat. The only bloat you might get is from gastrointestinal upset.
It does not cause bloating elsewhere, despite what people say. It is transported into muscle. It draws intracellular water. It does not make a big impact on extracellular water, so claims of loss of definition can be due to some kind of allergic-type reaction or the fact that people eat like crap a lot of the time when their metabolisms are simply not particualrly fast. Then they blame their fat gains on the creatine if that happens.
I've used creatine while bulking and while cutting. When cutting, it makes me appear even more cut because of the cell volumization, which enhances the appearance of my muscles. When bulking, it does the same, but I have fast metabolism. Someone with a slow metabolism will eat to bulk, take creatine, get fatter because he is bulking, and then look to demonize the substance.
