Yeah been there done that. For me it was a poly-addiction to benzodiazepines and amphetamines, former for work to quell the panic attacks that I'd be fired and deported back to the third world and the latter to play new vegas on the weekends. At the time it was an improvement from a 6 pack a day and a bottle of gin on the weekends. It was a long road outta all that, but trust me, there's a light at the end of the tunnel. I don't even drink non-socially anymore.
