You may be aiming to relieve depression, which chocolate will do. Recently, scientists discovered that the anandamides in chocolate and cocoa powder activate the same receptor in the brain as marijuana. The result is a sense of well-being or mild euphoria. Dark chocolate would be my choice. There are some benefits to chocolate, too.
Chocolate contains phenolics , the same type of antioxidants that gave red wine sales a major boost.
Many people who are addicted to alcohol easily get addicted to other substances. Try to use chocolate as a way of rewarding yourself for good behavior, instead of eating it mindlessly. Eat it consciously, and in moderation. Once you've stabilized in your alcohol recovery process, you should be able to address this less dangerous addiction too. Sometimes naughtiness can feel pretty nice.
