I am 17 years old and have had CFS for 4 years. Despite using precautions, I became pregnant and am now 31 weeks. Since being pregnant, I've had 2 chest infections, a bulging disc in my back, shingles and now SPD which means that I have to use crutches constantly and a wheelchair for any distance. My ante-natal consultant believes that I can go for up to 12 hours in labour without needing an epidural, and will be able to manage on isotonic drinks. I didn't think isotonic drinks were good for you if you have CFS, but am I wrong in thinking this? Please can anyone help me with any useful info and also how long anyone's managed in labour without being too exhausted to give birth, as this is what I'm worried about. Many thanks.
