I would say there is no "normal" when it comes to recovery. We have good days and bad days, whether we are drinking or not. And when we are sober, everything is magnified - the good and the bad. I do remember that day 2-4 were usually the absolute worst for me. Also, it's thought that each detox gets progressively worse...so you might be experiencing some "kindling" as you cycle between drinking and sobering up so often.
Either way, keep at it - you are trying and that's what's most important. It will get better, that's for sure!
