How will I know what does an alcoholic like me do to ease withdrawal symptoms?

Slowly reduce. Alcohol withdrawal is one of the few withdrawals that can be life threatening. If you can't reduce the amount your drinking gradually, you may want to find a rehab or detox to assess you and keep you safe, to avoid seizures and delirium tremens. Staying in a low stimulation environment can be helpful, and trying to relax and avoid stressful situations can help.
