No matter how long they last, remember that cravings are simply feelings. They only exist as thoughts inside your head and they will go away. You have 100% control over how you react to them.
Also remember that you are on day 11. That's a great accomplishment but still very, very early in sobriety. These feelings will subside both in intensity and regularity over time.
Read some posts and write here, join the chatroom read a book, take a nap...lots of things you could do. Also make sure you aren't hungry....hunger pains can feel a lot like cravings too.
