Natural birth vs epidural

Raeleigh
Here's what happened to me with my second child 
With my second the doctor (won't admit it even tho the nurse said to him he did) gave me too much. My 13 year old sister was with me when they put it in and instantly my legs went numb like they are supposed to... Then it hit my stomach arms and chest ... All the way up to about my chin. Scared my sister so bad. I couldn't breath well my blood pressure plummeted I kept puking but every time I puked i couldn't cough it up, I had no control over the muscles in my mouth or throat so Id start choking on it. Hours later I had my son and the numbness finally was just my legs, but it should have worn off completely by then. I'm pregnant with my third and I'm very scared to not have one... The near death feeling experience I had with my second son I never want to go threw that again.... But very nervous on having a natural birth 
I'm scared to ever have another epidural... But also have no idea what to expect with having my child without one. Both my boys before I had to be induced so I know that makes the contractions a bit worse too. But still.. Any advice or tips or even how it felt to do it with no epidural????? 
This is my third and last baby. My first son is from my first husband my second my fiancé was away on work and couldn't be there... So I want this to be memorable for him to, not horrific and scary... Like it was for my sister last baby.
