yes the heat has been brutal....crz weather this yr!
i used to live in an attic apt. w/o ac. in summer it would be really steamy. one night in desperation i filled up a shallow pan with ice cubes, put that in front of a fan and i sat in front of it. it worked!
well, not like ac, but try it and see if it helps. it got me thru.
best wishes, nowisee
