Hide that I take laxative?

Hello

I told my friend about my upcoming colonoscopy and the laxative. He's actually pretty nice and says he has no problem with it and can take care of me that evening.

But I don't want to seem so helpless that evening. Can you hide something like that?

So I'm definitely going to have to go to the toilet because of the laxative, but can I somehow control that? So that it doesn't look like I have extreme diarrhea
