I caved @ 24 hr. I had to go buy food for the wife (TOM) and kiddo - Hyper @ spring break. I caved to those smells. The day was lethargic and I had to de-stress from my nightmare week of on-call. I tried to resist, and was doing OK in spite of being super super sleepy. I should have slept instead of going to buy dinner for the 2 lovelies.
I also have to have a end date/time in mind, I cant fast till something happens in my body. I will tentatively set myself a target of Saturday the 15th.
Anyway I got used to a 24 hr on water alone. Hopefully I can do 48, and I believe 48 is where it starts to get easier. Then I can stretch it past 15th.
