I remember how that feels @Kaityrose, it will pass in a few more days so hang in there. The first week and in particular the first 5 days were tough for me, I thought it would never pass but it does. You are doing great to get to this point so keep pushing through.
After about a week your body starts feeling better and your mind follows soon after but start making proper sobriety plans as soon as you can.
Make lists of reasons why you want to be sober etc, keep checking in here and if you are open to the idea perhaps try a support group. AA really helped me in the first few weeks, I went feeling terrible to meetings, but always left feeling a bit better afterwards.
