Hoosier, the SF Pudding isn't allowed on Phase 1. Just SF Jell-o and No Sugar Added Creamsicles, Popsicles, and Fudgesicles. There are starches in the pudding which will stall your weightloss. Consider tomorrow a start over and stay away from the pudding until Phase 2.
In the meantime, I'd go see a doctor, just to be sure, okay? And make sure you are drinking lots and lots of water to combat dehydration.
