Reminds me of my last drink. It was a bottle of bacardi (750). Bought it at the store because it came with a neat mohito making utensil. My design was to eventually make mohitos at some future party. Decided to have a one drink and ended up downing the bottle over the course of an afternoon. Ended up d-dialing in the worst possible way. Decided it was my bottom and have moved on. At
about six months now dry and life has improved exponentially. You're young and shouldn't obsess about withdrawals; you'll likely feel crapy for a couple of days, but that's about it. Make sure you stay hydrated and eat decent food. Most importantly find stuff to do that replaces the time you used for drinking.
