Live and learn. Sounds like you'll figure out what's right for your body!It wasn't just the weekend that was tough though, it was every waking moment, in my wifes case even when sleeping it was difficult because she would wake up in the middle of the night just starving.
Nuts are good in theory and work for lots of people. It just happens to be something that I'll occasionally go cookie monster on. When I find one of my danger foods, I'll give it away or throw it out. If I really want it, I can drive 5 minutes to the store. Cookie monster doesn't show up for veggies, fruit, meat, and protein bars.
When I get the munchies at night, I go for protein like slices of low fat turkey. Then I'll top off with lots of veggies. Maybe a snack before bed. I eat a fair amount at night, so I don't go to bed hungry. I'm able to do this, because I can manage with around 600 cals until dinner time. Weekends are harder, because I don't have the distractions and structure from work. That's just what works for me, and I'm still making minor tweaks. Good luck!
