Normally after you have successfully quit all of your addictions, you will be left with just food to battle with. Your body obviously needs food to live so you can't just not eat. When our body is in a state of imbalance and it is trying to rebalance itself, you will tend to overeat simply to counteract and alleviate the anxiety you feel both in your body and mind. It is easy to try to compensate for the loss of an addiction by nervous-eating and it can cause you to gain a lot of weight real fast. This can be depressing in itself but you must remind yourself that in time your body will rebalance itself chemically and you won't feel such a need to snack all the time.

Exercise can be really useful after quitting an addiction because it helps to relieve the physical stress you are going through from the slow withdrawals, and it also gives you a positive habit to fill in for the negative habit (the addiction) you just surrendered. Even if you just walk aroung the block, or even in a circle around your living room, it can help to jump start the healing process in your body and mind after you have quit and addiction. Try to be balanced though in your exercise, and to not just make it another obsessive addiction. Ask God to help you with your exercise and allow Him to be in control of your recovery.
