I didn't use an epidural with either child as I'd read too much about how they greatly increase the percentage of c-sections. I was more afraid of that than contractions, but that's just me. Birth hurt like @#$# but I survived as did the babes. My second babe was so fast there wasn't time anyways.
No judgement here though for those who do. But you can get through it without if you have good support and coaching before the big day. Non-husband support - people who understand the birthing process. My babes arrived long before we arrived here so I'm not sure how well Singapore is set up for midwives, doulas etc? They can be fantastic if you try it without an epidural.
Either way it will be a great experience.
