"Evening sickness"??

I'm 9 weeks as of yesterday. I started out with a little nausea in the mornings but that lasted about 2 weeks. For the last two weeks, I feel like I've got the flu in the evenings! Around 5-6pm, I get super fatigued, nauseous, can't eat, and I vomit (mostly dry heave) several times a night. Then I sleep pretty well and wake up feeling pretty good, with only random waves of nausea. Any recommendations on how to decrease this "evening sickness"? My house looks like a disaster and I'm tired of it feeling well when I finally have time to spend with my husband after a long day at work.
