It could be signs of PAWS (post acute withdrawal syndrome) and that's the changes in your body and mind while it's adjusting to functioning without alcohol. It will get better. It also helps to have any support system to help you thru those rough times. I see a counselor once a week and it helps to be able to vent and get her excellent feedback.
I'm near six months and a lot of that stuff is fading away. Sleeping better and feeling more 'balanced', mentally and physically.
Don't let this stuff get you to relapse mode. You can avoid that by just not picking up the first drink. Remind yourself of the poison it truly is.
You can do this. And if you don't start feeling better in the near future it might be a good idea to see a doctor for a checkup.
