Hi Catchement and welcome to SR.
Your story is typical of the progression in an alcoholic. We drink at first because it makes us feel great. We continue to drink to continue to feel great. The mental obsession, the "why nots", drives us to drink despite the fact we know what the consequences will be.
Eventually alcohol stops making us feel good but by this time we are addicted and we have to drink. The more we drink, the worse we feel. The one thing all of us alcoholics have in common regardless of how long since the last drink, is that once we take the first drink we are thinking about the second, third and so on.
Alcohol is a drug which directly affects the Central Nervous System. Each time you drink you are damaging your brain and CNS. Tremors are a sign of the damage of the nerves which regular, excessive consumption causes and also can happen during alcohol withdrawal.
The brain and CNS can heal over time if you abstain from alcohol, but not all the time. Some people are left with permanent brain damage from drinking alcohol. Some people are not that lucky, they actually die.
The fact that you are a daily drinker suggests you may already be physically dependant on alcohol. People who drink beers can need a medicated detox to withdraw from alcohol as well as people who drink liquor. Withdrawal in itself without medical supervision can be dangerous and result in permanent disability or even death.
Please think about being honest with your doctor about your consumption and your tremors. Most people are unable to quit alcohol on their own. AA is a great place to get support from people who understand how you feel and also in AA we have a program which works - it removes the insane mental obsession to drink alcohol.
Take care.
