Morning sickness! please help!?

I am 9 and a half weeks pregnant, and my morning sickness is out of control. It is an all day, every day thing. I have phenigren gel, and pill form but it doesn't help. Also, i have tried ginger ale, lemon water, setting snacks by the bed to eat before i get up, anything i can think of, and it doesn't help. I haven't had a lot of vomiting but the nausea is getting in the way of college. I have missed several days, and I NEED college more than ever now that I am going to be taking care of another little life. Any tips for the nausea would be great, and if anyone knows if a doctor will consider giving a doctors note for school for morning sickness so that i can at the very least take my exams late and not be punished for lack of attendance that would help me out greatly. I know it will p soon, but I just feel like I can't handle it much longer!
