You can't eat what's not there... if others in the family HAVE to have the treats that look better to you than what you CAN eat...they can at least put them in one place...so you know where NOT to look... the fewer "cues" the better.

It makes it easier for me to pass up the poor choices when I have better choices handy. I make a batch of lc muffins (ketogenics brand is my favorite) freeze them, and nuke one when a craving hits. Having cheese and veggies, nuts, pork rinds, etc. handy helps too.

Sounds like it might be time to do a little soul-searching to figure out what makes you give up when you get to a certain point. Sometmes we have "roadblocks" set up that get passed off as boredom or "falling off the wagon"...

Whether you think you can, or you think you can't..you're usually right.
