I too have been experiencing this agony. Its just non-stop anxiety for the past 5 days since I became sober off alcohol. I'm not sure if that is normal. The only time I feel somewhat at ease is late at night.
Anyway I find it strange because I have drank the past 3 years almost every night, and when I did stop for a few nights I never felt anxious. (I quit for 3 nights around christmas time and felt fine, although I do remember my muscles tensing up at times).
Now a month later, going through my first real sobriety (which is almost at 6) days, i'm an anxious mess for just about every waking second. Is this recovery or GAD?
