If i have some neurological problems, should i stop buying beer cold turkey and get some bedrest and rehydrate?

Talk to your MD: What kind of neurological problems?? If you have been drinking heavily enough to cause nerve or brain damage, then you need to talk to your doctor about the potential for severe withdrawal, including very high blood pressure, seizures and delirium before stopping. You also need help beyond stopping, hydration and rest - you need evaluation for a treatment program. Glad you want to help yourself.
