^ Nestler EJ (December 2013). "Cellular basis of memory for addiction". Dialogues Clin. Neurosci. 15 (4): 431–443. PMC 3898681. PMID 24459410. Despite the importance of numerous psychosocial factors, at its core, drug addiction involves a biological process: the ability of repeated exposure to a drug of abuse to induce changes in a vulnerable brain that drive the compulsive seeking and taking of drugs, and loss of control over drug use, that define a state of addiction. ... A large body of literature has demonstrated that such ΔFosB induction in D1-type [nucleus accumbens] neurons increases an animal's sensitivity to drug as well as natural rewards and promotes drug self-administration, presumably through a process of positive reinforcement ... Another ΔFosB target is cFos: as ΔFosB accumulates with repeated drug exposure it represses c-Fos and contributes to the molecular switch whereby ΔFosB is selectively induced in the chronic drug-treated state.41. ... Moreover, there is increasing evidence that, despite a range of genetic risks for addiction across the population, exposure to sufficiently high doses of a drug for long periods of time can transform someone who has relatively lower genetic loading into an addict.

The second reason is because you want to do your recovery on your own. You've always been self-reliant and you want to be self-reliant in your recovery. But recovery involves learning to ask for help. Doing it on your own is overrated. You need to ask for help from your doctor, treatment program, 12 step group, and sponsor. Antabuse is just one more thing you can use. It is not an alternative to your supports. It complements them.

As with treatment for most substance abuse problems, there are two angles to treating an alcohol problem. The first step is to break the physical dependence on alcohol. As mentioned above, cutting off alcohol after developing an addiction to it can cause withdrawal symptoms that could be severe enough to drive a patient back to drinking. For that reason, the detoxification process of treatment often involves the careful administration of drugs like anti-anxiety drugs to help wean the patient off their dependence on alcohol and through the process of acclimatizing to life without alcohol.
People intent on abuse discovered that crushing OxyContin tablets allowed them to inject or snort the drug, producing an intense high similar to that of heroin. Crushing the drug also eliminated the time-release mechanism of the tablets, greatly increasing the risk of addiction. And a recent study found that OxyContin is a gateway drug for heroin, which addicts may prefer as a less-expensive alternative to OxyContin.18
There are many reasons people get addicted to drugs, but you must gain insight into what draws you towards your substance of choice. Is it a means to cope with stress? Do drugs help numb you emotionally so you don’t have to feel emotional or physical pain? Are drugs a way to avoid responsibility, gain other’s approval or belong to a group? It’s important that you peel back the layers of your behavior to understand what is behind your drug habits.
In most parts of the world, alcohol is legal for adults to both purchase and consume. As a result, beverages that contain alcohol are available almost everywhere, and clearly, many adults partake. Since use is so common, it might seem hard to determine who is drinking alcohol in an appropriate manner and who is drinking in a manner that could lead to alcohol abuse or alcoholism. Experts suggest there are key signs to look for.
Research the history of the Treatment Center or facility.  What is their success rate?  Can you find any medical recommendations for them online from members of the established rehab or medical community?  How long has the Center been in operation?  Is their leadership on solid ground?  Are there any signs of financial corruption associated with the Center that is readily visible on the Internet?  It is your responsibility to dig for this information.  If you cannot find any information about a given Treatment Center online or at your local library, move on to the next Center on your list! 3 Stages of Drug Alcohol Rehab-How It Works
