Coolers

The problem with alcohol is that it neither cools nor refreshes; it makes you drowsy then it disturbs your sleep.  But, it is something to take your mind off of the heat.

Easy Cooler:

Fill a tall glass with ice.  Add 2-3 ounces sweet vermouth.  Fill glass with Diet (or regular) 7-up.
Sip.  Nibble with a few nuts.  It's too hot to cook, anyway.

Repeat.
