I went to a doctor at 50 days and was experiencing similar problems. I was asking about some meds that I used to be on and he told me to wait another 40 days and see if I am feeling better. The Doc I saw specializes in addiction, and said it's going to take more than 50 days to get my body and brain "back to normal". He said he would put me on meds if I really felt like I needed them, but I guess it's going to take more time for my brain to adjust to not being drowning in alcohol and drugs.
I have been sleeping almost 12 hours a night, and was a bit concerned about this, but the Doc assured me this is normal as well. I guess having my CNS depressed for so long resulted in my body needing more sleep than normal.
This is just my situation, I know not all bodies are the same, and not all addictions produce the same physiological results but I am in a similar situation and I had the same questions.
