Maz,
I've had a permanent ileostomy for almost 22 years now. I'll try to recall my experience pre and post surgery, but as Bill said, it's different for everyone.
The day before my surgery, I had to do a prep like you would for a colonoscopy to clear my system. I think that was the worst part to be honest. Clear liquid diet but your health professional will guide you on that.
A normal ileostomy surgery with no issues will probably get you out of the hospital in 5-7 days. When I woke up, I had a tube in my nose, down my throat so they could flush my stomach. I wasn't allowed to have anything but ice chips the first few days but then they let you have clear liquid and/or soft surgical foods.
The doctor wanted me up and walking around as soon as possible. I wasn't in pain but I was sore. The air that they put in your body during surgery has to dissipate through your skin and it takes a week or 2. I felt hunched over and was scared I was going to rip my stitches out.
Oh, the doctor told me the sooner I was off of pain medication, the sooner I could go home so I had them take the morphine drip off right away. I wanted out of there. But I was careful and didn't overdo it.
So my advice to a person having ileostomy surgery is this:
At least 3 days prior to your surgery, go out and eat your favorite meal/s if your system can handle it.
Well before your surgery, try to put on a few extra pounds as you will lose a lot of weight right after surgery.
After surgery, be very careful moving around and do not do anything too quickly or overdo it. Your body will heal but it takes time. No heavy lifting as you don't want to risk a hernia.
When you do start eating normal food, remember....CHEW CHEW CHEW. Chew your food up VERY well. The more you chew your food, the easier it is for your body to absorb nutrients and digest and the less of a chance you'll have an obstruction. You'll want to avoid stoma obstructive foods right after surgery, but eventually, you will be able to eat those foods in moderate portions. Below is a card I found on this site that lists certain foods and what they do.

Stay confident. The ileostomy causes some people to have warped body issues. Do not let the ostomy define you. You will still be you.
