I am about 8 weeks pregnant and I have really bad morning sickness?

I am about 8 weeks pregnant and I have really bad morning sickness that lasts all day. I am not throwing up every day but I spend the majority of my time in front of the toilet. I have tried everything the books say, eating crackers before you get up, ginger teas or ginger ale, hard candy, bread, flat soda, eating small meals and not letting my stomach get empty, everything the books tell me. Nothing seems to work for me though, I cant even get anything done. I was wondering if anyone had similar problems and found anything that works for them. I would love some advice, I've talked to my mother but she had no morning sickness throughout the entire pregnancy. I have a doctors appointment tomorrow but I would still love advice. Thank you.
