Everybody has given some great advice. Getting a medical detox is a great first step. The 1st one I went through was scary as hell but only 4 days inpatient and I started on a friday and was out sunday night. I only took 2 days off work. In hindsight I wish I would have taken more time to do the residential (which i did 6 months later after relapsing), but at least it will get you clean safely and I'd recommend the 90 meetings in 90 days. If you tell them you just detoxed you'll find ALOT of support.
