So when I am drinking, sometimes I have these uncontrollable shakes as I drink down the vodka or rum. I do drink often, however, it can't be withdrawal because I still quite obviously have alcohol in my system. All I was able to find was how alcoholics can suffer from seizures and shaking after quitting drinking. Moreso, these shakes are quick and as I am drinking. And to be frank, it won't stop me from drinking, but I was curious as to why my body experiences this.
