Its very individual with the shakes and I think its also depending on how much neuro damage you´ve done to your brain.
If you have shakes more than 6-8 weeks I would ask your GP to get MRI scan.
I had to do the same. Was told that shakes and other more minor symptoms can take up to a year to be repaired. I.e brain functioning etc.
Shows how serious drinking really is and how ignorant we can get to our own health while drinking.
I used to think as long as I had a couple of weeks off here and there, I was fine.
The good news is that as long as you stop drinking in time before any serious damage, you will fully recover and can live a long happy life without alcohol :-)
