I am just over a month sober and also dealing with anxiety. It's worst first thing in the morning. I go from being asleep to wide awake with a pounding heart in an instant. It does seem to be improving the longer I am sober. I expect a couple more months of heightened anxiety as I went through this before. Anxiety attacks are the main cause of relapse for me as even just a couple pints of beer can instantly bring me out of an anxious state
