Yeah, I feared withdrawal as well. Probably kept me "out there" longer as I used it as just another reason to continue my destructive race to the bottom. I drank every day for over 10 years.
I offer no medical advice, however, I do suggest getting a program in place to stay sober long term. I found the fellowship of AA and the 12 Steps as the cornerstone of my long term sobriety.
Good luck and keep coming back.
