Sutab prep in 5 hours - I am so nervous

Hi all. I'm 26, and have my first colonscopy tomorrow morning. I'm not really nervous about the procedure itself but I'm not looking forward to the prep. I don't even know why I'm so nervous about it. Maybe I'm just looking for someone to tell me it will all be okay.

I took a look at the pills today and they're quite bigger than I thought. I usually need to eat something to help me get larger pills down but that's obviously not an option lol.

I'm a little nervous about getting nauseous from all of this. I wouldn't necessarily say I'm emetephobic but I've never vomited before and I don't want to.

I wish there was an easier way to do this! But I'll get through it if it's for my health.
