When I stopped drinking my anxiety was literally through the roof. I couldn't sleep, lost weight, had to pee constantly, horrible dizziness / wobbliness and literally couldn't watch TV or deal with any amount of stress.
Best thing for me was to get some sleep and my doc prescribed Trazodone for that. It along with an anti-depressant and a non-benzo anxiety med did the trick.
Anxiety takes a while to ease up but it slowly does as your mind's neurotransmitters get back to homeostasis. For me the mess helped ease the distress during that process.
Six months sober and things are almost back to normal and the anxiety, while not totally gone, doesn't even feel like anxiety.
