Answer
Yes. Absolutely. Vicodin is a depressant in and of itself. It works on brain chemicals to suppress reactions to pain which also suppresses reactions to pleasure as well. Since it has such a psychological effect on people it is alot like marijuana use...once you are used to being on Vicodin or marijuana, the world seems to suck alot more when you are not taking it because your brain is more alert and responsive to every little thing. Hope this helps! :) Good luck! Best thing to do is to taper off slowly.
