Hi April..

It's all MS carp. April. The weakness, brain fog and dizzyness, from the heat. I once sat in the hot sun for awhile and when I tried to get up....I couldn't. I splashed ice water on my legs and then could move them enough to walk inside to the A/C.
I now stay out of the heat, all together.

But, when I was younger with small children, I had to find ways to go into the heat. It's not easy, April, but there are a few cooling tricks...ice water always, cold packs, cooling vests, head bands, scarfs and wrist bands for cooling.
Feel better soon.
