I hope that you don't consider yourself helpless against an incurable disease and destined to drink. Whether or not you have a disease, you are addicted to an addictive substance.
Bupropion (Wellbutrin) gave me headaches for a few days and then changed. So, you could stick to it for a while and the headaches might go away. I drank on it once and felt horribly depressed the next day. So, it acts like antabuse for me.
