memory loss
I have found that I cannot remember past events while I was using. My husband says remember when we did this and all I remember is being more drunk on that specific day. That is all part of using alcohol and drugs it happens to everybody at any age. But that is in the past and to change it would be to change what has brought you to recovery. I do know that once you stop drinking you have way better chance at retaining things as you get older than if you were drinking. It is a great first step, add a few vitamins and mind working techniques and you will be very sharp.
I hope when you go back to work the skills you need come back to you. If they don't ask for help, people notice when you are in recovery and want to be around you.
