MAGIC....yes it can be rough...i remember when i was a couple of weeks sober and was having the same vomiting that I had prior to stoping drinking...a part of me wanted to give up...I was like...whats the point. I would go out in the courtyard in the mornings and from 6-6:30 people knew I would just be crying and that I would get over it and go on....
It was worth getting through it...i havent gotten sick to the stomach in about 4 months now and it had been about 4 months before that that i had been sick before....after about 6 weeks sober I had very little problem.
So stick it out cause if you drink it will end up getting worse not better!
