I have had 3 epidural births and my last birth was natural with no meds.
With my first, I had the epi during transition and gave birth not long after. I absolutely loved the epi and the relief it brought and honestly couldn't understand why you would want to do it any other way

For the next 2 I basically had the epi as I walked into the hospital because of my first experience

Then with this last birth I had been doing a lot of reading up and realized it was more fear than anything else that made me unable to cope and decided to give natural a go. It was an amazing experience although during transition I went though a lot of regret for not getting the epi. Afterward I felt like superwoman !
Honestly, I think there are advantages and disadvantages to both. With the epi everything was calm and relaxed (I was lucky not to need any interventions and pushing was really easy) but I didn't enjoy having a drip, catheter and not being able to shower after. With the natural it felt chaotic in the end .... 7 to 10cm in 5min with the nurses trying to get me to not push while the Dr ran up the stairs (yeah right

) but the feeling of euphoria and achievement was incredible. If I had to do it again I would have natural although I know hubby would prefer me to have the epi

Having said that, he is constantly mentioning to everyone that I had no pain relief ... I think he is really amazed lol
I would say be confident that you can do it, but be prepared that there may be a time during transition that you will wish you had chosen differently. I was very vocally scolding myself for doing too much reading on natural births

When you get to that point just remember It will pass and as soon as you push that baby out and you will not regret your choice to go natural !
