ITs not that sobriety sucks, its that detoxing after being intoxicated for so long sucks. Trust me on this point. I went through the anxiety, dreams, etc. They all fade eventually as you fully detox (that takes months, not weeks or days), then your brain has to detox (subconscious as well) and that takes about three months.
You just have to bear up and be strong, when you are feeling weak, come here and ask for help, go to a meeting, talk to your HP.
