Getting induced Monday night but lots of questions!!!

We're going in Monday night at 7:00 to start this show! However, I have NO clue what to really expect. They're going to start with medicine to help thin out my cervix first, and then I assume start pitocin later? I know that's going to be a long time to not be able to eat. What/when should I eat before going in? Do you think bringing a Gatorade to sip on for later would be okay? When I was checked Thursday, I was dilated 1 1/2 cm so I know this process could take a while. Any suggestions or any advice is welcome!
