This thread helped so much when I was detoxing. I was so glad to read others similar experiences so I knew my symptoms were "normal." Maybe my experience will do the same for another. I was a constant fifth a day guy for three years. Vodka and whiskey were the poisons.
I don't remember the days, because I unplugged the clock and shut all the drapes. I just wanted to get through it. I brought 5 cases of water and a ton of movies into the bedroom and shut the door.
My symptoms: (basically, it felt like a really bad flu)
Chills - I couldn't get warm. I turned the furnace up and up, but I couldn't get warm. Only a shower helped. Someone else said "compulsive showering." I had that too. Only to be contrasted with...
Sweats - If I managed to sleep, I woke up soaked in sweat. Sweat was coming out of my scalp, even my feet. I kept reminding myself that it was my body purging itself. I'm not kidding though, I literally must have sweat off a gallon or so. Showering a lot for this too. The best way to describe it is like camping when it's raining or maybe living in Atlanta

. Just very humid and sleeping with wet comforters.
Liver pain - just a constant tenderness.
Severe dehydration - my skin felt like it was on fire, if I scratched it burned. And, I had to replace all that sweat.
Bad heartburn - this was the worst for me because I'm such a baby when it comes to that.
Headache - the kind that only vomiting makes go away.
Nightmares - when I finally started dreaming again, they were incredibly vivid and scary.
I didn't have shaking, major vomiting, hallucinations or seizures. I'm very thankful for that. It's been over 30 days and I still occasionally sweat all night.
Sorry for the long share, but grateful for the opportunity.
