When did they start to feel better?

My daughter started with a fever on Friday, and the fever finally broke Monday evening, and she seemed to be feeling better. The rash appeared yesterday morning, and she screamed all morning long and slept most of the day when she wasn't crying. Then this morning, she has been so lethargic and irritable and won't eat solids at all, but I thought she would be feeling better now that the fever is gone. We have a follow up appointment tomorrow, but I'm trying to gauge if this is typical with roseola.
