Hi Chris,
Your story doesn't sound strange at all. Lots of us have concerns about various health issues due to drinking. We can do a lot of damage to our bodies. And, the sleeplessness and scary feelings are part of withdrawing from alcohol. You might check with your dr before you stop drinking because there can be problems withdrawing. It's not a fun thing to do, but it can sure be done and you can begin to regain control of your life.
I'm Anna, recovering alcoholic and I'm glad you found us.
Anna
