I just found out I am expecting twins!!  I'm so excited!  But I'm worried about the possibility of morning sickness!
Oh congrats! I had minor morning sickness with both my girls, just nausea. 
I just hope I don't throw up!  I hate that!
YEah, I never actually vomited. I just felt nauseous, all day unfortunately. 
I've heard that eating crackers helps - is that true?
Yes, crackers work for morning sickness, basically, a bland diet. 
Maybe there are medications to take in case the crackers don't help?
I think there are some treatment options, like taking doxylamine, but most moms just tough it out!
