Welcome - glad you're here! You really can have a better life without alcohol/drugs. Just take it one day at a time (and do call for help if you need it - I guarantee hospitals see lots of folks like us).
Also, check out the section on substance abuse - you'll find lots of support there too:
Substance Abuse - SoberRecovery : Alcoholism Drug Addiction Help and Information
Congratulations on day 1 - hang in there!
