I had learned in school while taking an course on addiction is that drugs and alcohol effects the central nervous system . I had to learn about it on how to supports individuals with Fetal Alcohol Syndrome Disorder.

Think of your central nervous system and brain as an electrical box. Each curcuit breaker is built to control certain areas of the house. Just like each area of the brain controls your central nervous system, which then tells your body how to function.
If just like the electrical wires in the house, if ithe wires gets damaged, the electricity in the house wi not work.
In the body, when someone is abusing drugs and alcohol, the messages from the brain, through the central nervous system to the body parts do not communicate properly. It can take a long time to "rewire" the brain to communicate with the rest of the body.
I have enclosed a couple websites that might help explain more to you.

Could it be the stress of your situation? I know that large amounts of stress are my triggers. I wonder if it could be the same for you

Pray. Ask God to help you. And get a second opinion. There’s got to be something to control them!! Sending prayers!!!
