If you are taking Cell-Tech then you don't need to worry about taking it with any other form of simple carbs like dextrose or fruit juices. That is already contained in the 75 grams of carbs per serving.

Feeling bloated with creatine is not abnormal when first begin taking it, but a major cause of this is probally the fact that you are taking in 24 oz of water in one sitting. Also the simple carbs of dextrose can make you feel bloated and make your stomach upsetwhen you first begin taking it. It took me a while to get use to that much sugar at once. I don't understand why you are taking an extra glass of water after that but its your choice. I just think thats alot of liquid.

Also give the creatine time to show up in your muscle size and strength gains. Just like anything else it won't happen overnight.
