Entonox ('the gas')
Entonox is a mixture of nitrous oxide and oxygen which is
inhaled through a mask or mouthpiece. It is effective almost
immediately, and the effects will peak after one minute, so you

focus on to get me through contractions so worked in that respect.
Seemed to do nothing for the pain tho! "
"If you keep your eyes closed when breathing in the gas
you don't get that dizzy, sick feeling."
