Just read thru your latest posts INH, the tone of them seems to say "I don't really like where I'm at or what I'm doing". Something to consider is that you only get so many years to stroll around this planet, why waste them going thru the motions in a position you could care less about.
Don't know what your options are but it seems that a transfer out of there might not be the end of the world. If you have zero interest in staying in after your time is up then in the whole scheme of things maybe just laying your cards on the table might not be such a bad idea. I would never tell them about the drinking tho, having that on your records can and will come back to haunt you. Anyhow, hope it all works out for the best.
