Boozefree , i recall being at work and unable to concentrate in second month and some in third month, and thinking if this doesnt get better how will i ever function at work? It took awhile but it did get better though. Now it is dramatically better!
Hang in there. Remember your body is depleted especially of folic acid, magnesium, thiamine, etc. Why don't you start making sure you have a daily good multi vitamin plus minerals tablet and take it everyday? Even doing that, it will take awhile for your body to catch up, but it will.
Please don't let these things stop you from your sobriety. This is part of getting clean. If you don't muscle through now, you will have to all over again. So power through this part. We are here for you.
