We have done a couple 24 hour fast at my church. But the first time I tried to do it, I got really dizzy and almost passed out. Turns out I am insulin resistant and the lack of food made my blood sugar plummet. So I haven't done it since.
Heck yeah! Because I hate exercising, I get no enjoyment out of it. But I wish I did so I would exercise more. If I just took a pill then I could get on with my life and not worry about it!
