Praying your DH will get better soon, Jemian.
I think he will. He feels bad at night, but then, in the AM he feels so much better he starts doing stuff. Then, about 3 PM he feels worse so he “guts through it.” Repeat.
I wish he would just go to bed for a day or however long is necessary and be done with it! All, I can do right now is stand back and make sympathetic grunts as he mopes about.
