Daughter is making herself sick

For the last month my husband and I have been putting out 11 month old daughter to bed and doing the controlled crying method. She was fab for the first 3 weeks. Would only cry for 10 minutes and then go to sleep. The last week she has been working herself up into such a state at night she screams until she throws up. I end up changing her bed about 3 times a night due to her being sick. Has anyone got any advice on what we can do? All she wants is to get into bed with my husband and I but with a baby due any day now, it's really hard to get any decent sleep as she constantly moves and kicks us
