Congratulations on 4 months that is wonderful.
Yep, I could be a little nuts at 4 months as well...
I would just tell myself it was time to pay the piper and it was my brain adjusting...
I would get these weird anxiety zaps that freaked me out. I felt like it was directly related to my alcohol abuse. I had PAWS as well.
Time did make all the difference and it has passed, however, I would not have hesitated to go to the doctor if I thought it was more than alcoholism recovery related.
