Anyone who is new to recovery needs to Google PAWS! My symptoms lasted for almost 5 months. And that was just physical, next came depression and not wanting to leave my house.
We put all this toxic crap in our body for years and expect to be magically healed after a few days. I'm at 7 months and, while it has gotten much better, I still have days where my brain feels foggy and others when I sleep all day long. Your body is healing.
Just get through one day at a time and be patient. Being patient is very hard, especially when you feel like you want to crawl out of your own skin (that lasted for almost 2 months for me and was awful) but it will get better. Just look to the future when all of this is over with and you never have to go through this again. The memory of what I went through is my biggest reason to staying sober. I will never put myself through that he!! again.
