Time will ease the strong desire but the desire will never go away if you don't work on the root causes in your life. Quitting for 90 days is big deal but you likely will drink again if you are not delving and working from the inside out. As an alcoholic my most natural reaction is to pick up a drinking. I have to constantly work on this and be aware of it. If you don't have a strong foundation the house will eventually fall. Just food for thought, best of luck friend
