I'm starting to get a little freaked out. some days i just don't feel like eating at all and feel sick at the idea - other days i feel like eating the whole time even though i don't feel the actual hunger and eat until i feel discomfort or pain.

has anyone else out there been through this?

Yes. I have days where I think I could eat the farm and other days when I hardly eat anything. Since my last fill though, I am eating very little and becoming more satisfied with that. Consequently, I have been losing better. I feel perfectly restricted and very good at this point.
