Jello helped. I enjoyed the prep oddly enough because I had to fill my belly (mine was mixed with gatorade and I only felt nauseous for a few minutes).
I didn't mind all the shitting. The hunger wasn't fun, I ended up with a headache and I was sorta bored. I think I was so focused on the prep that I let my day become centered around that, unfortunately.

Walter: No, Donny. These men are cowards.
