Dear Panic,
I used that as a reason not to quit also. But the truth is, you have to go through it in order for it to go away. I had maybe 3-4 nights of not much sleep, shrivering cold one minute, sweating bullets the next. Also clammy sweats during the day, not very comfortable. But the good news is, it does stop. Now I fall asleep instead of passing out. I have come to understand that alcoholic sleep does not provide the REM time that our bodies desperately need.
I am only 13 days sober so far but my health (what I feel anyway) has already improved dramatically. Sleep is so much better, waking hours better too. Go for it, the rewards are great.
