I'm at week 4 and I literally feel your pain
The past week I have woke up with headaches not fair considering I haven't had a drop. For me it wasn't anxiety but anger about what I haven't a clue I am so joyful to be 4 weeks sober and I tried to focus on that instead of trying to behead someone. Today is much better and I am looking forward to my lovely sober weekend! Hang in there it does get better.
