End of day 2 Medifast

I really need to start a regular eating schedule. I am not hungry by the time the next meal rolls around. (Which is great so I don't feel hungry all the time!) However, since I'm not hungry, I put it off until I start getting s headache, light headed, and tummy grumbling. The dietician warned us about this for after surgery, so I need to get on a schedule now so I can safely lose weight.
