The term you are referring to applies to someone who has abused alcohol to the point that normal brain function is permanently impaired. There are several degrees of "wet". I have been on 12 step calls and witnessed this first hand. It is a "very awakening" experience.
If you were able to type a post here, then you are not likely wet brained. What you are going through is known as the "paws": Post Acute Withdrawal Syndrome. Now I am not a doctor and not trying to offer advise, but in my early attempts at sobriety were me trying to "study" this disease. I thought if I knew my nemesis, I could defeat it. Of course, this did not work.
The "paws" is caused by a sudden withdrawal of a substance that your body has become "dependant" on. After abusing alcohol and drugs, the brain stops producing certain chemicals such as dopamine and seratonin. The abused substance causes the transmitters and receptors in the brain to stop "firing" the chemicals. Once the abused substance is no longer ingested, the brain experiences a chemical imbalance. The severity of the paws related episodes depend and the frequency, substance used, and length of abuse. Most experts state that the paw starts 7 to 14 day into recovery and can last 3 months to two years. The severity of paws can also depend on the stress level experienced in sobriety as well. Here are some examples of paws symptoms:
1. Inability to think clearly
2. Memory problems
3. Emotional overreactions or numbness
4. Sleep disturbances
5. Physical coordination problems
6. Stress sensitivity
Do not fear this. It is merely a sign that the brain is trying to stabilize. There are things that help, such as exercise, proper nutrition, meditation, and most of all, working the program with the help of your higher power. In time, these chemicals will flow again. They call this "getting your brain out of hoc" in AA. Doctors can also treat with certain non addictive drugs, such as Serzone, or Zoloft. (Anti-depressants)
