Dolfinwolf,
Sorry to hear you are suffering today!
Its good to have a place to vent... where people understand.
Not sure if it will help you, but drink lots of water... I got a bit dehydrated in the heat the other day and felt AWFUL... after I came inside and cooled off I felt some better, but once I started downing lots of water, many of my symptoms subsided. Not sure if it was a coincidence or not, but maybe worth a try.
Take it easy today and feel better.
