Read my replies to the two post below this one, it may help explain some of your symptoms. Stopping the drinking and drug is a good idea - you'v emanaged to discover theat the best drugs are right there in your brain already - trouble is, you don't come down.
You'll probobly require medication, and i'd suggest taking it - but the primary managment strategy is to try to ignore it, reduce it to background noise if possible - engaging with what are essentially unconscious processes can be frustrating and endless, as they are essentially symbolic processes rather than cognitive ones - i.E., they only make sense in terms of your sub/unconscious organizational processes, which are extremely complex and chaotic - this sort of processing usually only comes to the surface in dreams.
In schizophrenia, your neurons are firing in random and unpredictable patterns, which can trigger these symboloic processes in the waking state, as well as memories, aural, holographic, even olifactory - so it can get pretty confusing, since these things are appearing spontaneously, and completely out of context to your conscious, cognitive state.
Physical activity might help take your mind off it if you can't concentrate on anything else, and I strongly suggest seeking professional help.
