hi StreamWader, days 4 and 5 are tough... i just went through the most horrid withdrawal myself (which is very fresh in my mind). you'll get better, just give it a few more days.
waking up in sweat is a good thing, although unpleasant... your body is getting rid of toxins. i couldn't eat for 5 days and could barely sleep. just like you i was afraid of not waking up if i went to sleep.
today is day 10, which is the longest i've been without a sip of alcohol in god knows how long. i can smile, the sun is shining again and i cannot believe that at this moment last week i was thinking that that would be the end of my days.
humans are very resilient... people have survived far worse things than that. i promise that it will get better. please come back here and let us know how you are doing, each minute without alcohol is a win for you.
