I totally agree with you. This heat is just to much. I also live in Tucson and it is just way to hot. I don't care that I have lived here all my life its still to dang hot to do anything.
I also feel that the heat could be causing stomach problems especially if you are out in it. Thank goodness I work indoors all day and don't go out until I have to go home.
I hope your tummy feels better soon.
Lets hope this heat wave stops soon and the rains start pouring in.
