HAHA!  Timmies!  Coffee for me is about the smell and habit seems it's the exact opposite - but I might give it a try.  Go coffee free for a month see how it goes... might, big might. :-)   Coffee has never effected my sleep, usually have a cup of joe after super with my son. I take it straight no sugar, no milk (or cream).  Good cup of coffee has the nuances of a good wine.  Like I said I might cut it for a bit and see... maybe :-)
