DWTBD and Tursiops are correct. Don't debate the voice telling you to drink. Just recognize it as your lower, undeveloped brain with an endless appetite for what it thinks it needs. Just dismiss it, don't debate.
You, on the other hand, are a mature, responsible adult who doesn't engage in harmful activity. You do not have a disease or a defective personality.
Learn to separate the two - the animal drive for pleasure and the mature adult - and you have it licked. Please check out the Secular Forum for lots of details on the technique known as AVRT.
