Morning sickness draining me 🤢 advice??

I am 7 weeks and this is my first pregnancy. Morning sickness/all day sickness hit me like a freight train this week. Any kind of food is revolting and mornings consist of dry heaving. I dread waking up in the morning and trying to sleep at night. I’m trying to eat what I can but nothing stays down until the evening. I’m glad I can atleast keep down the prenatal vitamins but I am not myself and I can barely function at my job without getting sick or nodding off. Any foods that won’t make me nauseous? Natural remedies or medicines? I’m willing to try anything I’m miserable 😖
