I have been fighting this insane fatigue issue for several years now. I sweat very heavily when out in the heat. I am from North Idaho, it is not so hot and humid there. I suspected I had been blaming it, partially, on recovering from my back injury. Certainly being laid up for as long as I was can make you weak. I just kept forcing myself to keep moving and it steadily got worse. Even though I was getting things done, it was taking the fun out of doing things(that and everything was taking longer than it should).
  I suspected I was sweating out a lot of minerals/electrolytes, and even took supplements off and on. Apparently not "on" enough. I stumbled across an article that explained why it takes 6 months to eliminate a magnesium deficiency. I also was looking into how much/long you can take supplements before it is toxic. I have changed my program. It is working.
I started something else.

Raw food shakes until the belly is flat again. I actually think I like this. I have been studying nutrition for quite some time. I was actually doing quite well with my eating and exercise before I got hurt. For a long time it was just survival mode. Now it is time to pick up the pieces and resume my life.

Installed one of the cat doors for Mary Beth. Bailey gave it a good study.

She ordered the other cat doors. Those will go in shortly.

Best of all.

The rest of the cushion arrived for my couch/settee. 3inches of super soft foam to top the mattress/seating part. 11 inch thick super soft foam for the back cushions.. Might sound a little thick on the back rest. But when the rest of this goes together in the next week, it will make sense. Should be extremely comfy.
