Hey Adelina, a lot of that sounds very familiar, for me I had very little energy to do much, despite then not being able to fall asleep, plus my digestive system was all over the place also.
Things will get better with more time, if like me and it took years of drinking to get to this point, it's going to take more than a few days for the body to adjust to not having what it has had for so long.
Though if you get really concerned about anything do check in with a Dr to be safe, you can do this!!
