My brother has or had now a drinking problem. Now he is asking for the worst tasting crap that he can take a cap full like an airplance bottle so his body whenever he thinks about it will remember

The taste and not just drink an airplane bottle. But the put a micro dose in the cap. Is there anything out there like that he is currenly doing could on this new pickle tasting stuff. Had the same small bottle over 3 months. Anything kind of similar?
