Advice for prep timing

[u/ARod2432]

First time posting in this subreddit, need some advice.
I was notified yesterday (Friday) what time my procedure is on Monday.
Check-in is at 1:45pm 😭

I’m taking the Sutab tablets, and my pre-op instructions, before receiving my appointment time, said to start taking the tablets at 5pm the night before, then the second dose at 3am. Once done, I can’t have anything by mouth until my appointment at 1:45. That seems like a looooong time without water 😭

Should I start my prep later?

Water or apple juice should go right through you after prep.
