I wanted a drug free labour and was well on the way to achieving it despite the best efforts of the midwife to get me to have gas, and epi, pethadine. My problems started when I began vomitting (something I tend to do when in extreeme pain, last time was when I had dislocated both hips at once) and couldn't stop. Here I was lying on the floor of the shower and violently heaving with every contraction. I knew at this stage the only way to stop the vomiting was with maxillon so I requested it, unfortunately the midwife decided that she would only get the maxillon if I had the pethadine... so I held of.. I hate pethadine and have had wounds packed with gauze drug free so new I could do labour as such... anyway I kept vomiting... after a while I began vomiting blood and in despiration to have the vomiting stop I consented to the pethadine, to get my hands on the maxillon.. to this day I feel cheated and bullied into taking something I didn't want and it is the only negative aspect of my daughters birth. I think you need a strong birth partner/advocate who will say what you want when your brain stops making the words you need.
