What changes in my body can I expect in the first few weeks after I stop smoking?

Well, the positive things that will change is that your carbon monoxide level will drop dramatically in the first three to five days, which means your oxygen level increases. That means you'll be able to breathe easier, you'll be able to exercise longer, and your long-distance endurance will improve. Pain that might have occurred previously, goes away. In addition, people's sense of smell often improves in the second week, as the toxic effect to the nerves in your nose are removed, and so your sense of smell starts to improve. Also, on the positive side, people start to feel better, and start to have more energy. But there's a negative side too; because you're no longer getting tobacco, or smoke, and that means your brain is no longer getting nicotine. So without medications to help you tolerate nicotine withdrawal symptoms, you will notice a change in your brain chemistry, pleasure center, irritability levels can increase, and also hunger can increase. All of the nicotine withdrawal symptoms can start setting in 72 hours to a week after you quit smoking and get worse, and then plateau and then get better.
