Eat chocolate! As long as you dont become obese its better for you than smoking by about a zillion percent! Also its not so weird, chocolate contains chemicals that mimic good feelings in your brain like love and satisfaction, as a result it is actually benefitting you in many ways. If you are worried about weight, go to the gym or just run or walk. Exercise releases endorphins that make you feel good too. Anything that helps pump those good chemicals in your brain will help you win over the bad ones from withdraw and addiction! Good luck, be strong!
