Dear B.,
Sorry to hear that you are having such a problem with morning sickness. I don't think age has anything to do with it, and after reading some of the other responses, I would also consider having hard candies and crackers by your bedside so that you can nibble on them BEFORE getting out of bed.
Do you have any allergies? I ask this because my girlfriend has had allergies all her life, and when she was pregnant, from the time she conceived until she was on the delivery table, she was sick as a dog. Her body was allergic to her babies - and she was pregnant four times, the last one several years after the second one (her third one was an ectopic pregnancy, so that didn't last long). She learned that cottage cheese and some other foods would help her along. She had quite a period of time between #2 and #5 kids because she adopted two children during that time (she and her husband were both only children and they wanted a big family). With her last one, she thought she was allergic to the OFF she was spraying on the kids during a bad mosquito summer, ended up in the hospital to have all sorts of tests done, and then found out she was pregnant again. Again, she went through the 9 months of nausea. I wish I could remember all the foods she tried, eliminated and was able to eat, but it was so long ago. I guess you'll have to try testing what foods will stay down for you.
I hope you are over your morning sickness soon.
J. B.
