A lot depends on your humidity. The higher it is, the less you can be helped by evaporation of sweat or cooling water. Lots of good suggestions here. I'd recommend not just drapes, but reflective ones, at least on the side toward the window, preferably that mirrored bubble-wrap. That will keep the drapes from heating up and dumping it inside.
Always be aware that running a refrigerator puts more heat out through the condenser on the back than you can offset by taking out ice to cool a room. Try to only run it at night with the window open.
